Hello, and thanks again for checking out my watch reviews! In this post, I will be looking at the Bliger 43mm Automatic Pepsi GMT Master II watch.

The version I bought for review has a Chinese movement (possibly the DG3804B?). I purchased it via auction from ebay seller ‘yangjianhai20167’. This is the first of two Bliger watches that I bought from this seller. Both watches came in individual plastic sleeves, then heavily wrapped in bubble-wrap pouches, and finally sealed inside a thick styrofoam shipping box. They were VERY well protected! No retail-box or papers were included.

KronoReview:

Bliger is new on the scene, like MANY Chinese ‘mushroom’ brands. You will often see them advertised on ebay, Amazon or various internet stores. They are typically sold alongside brands like Debert, Corgeut, and occasionally Parnis. The product pictures looked very interesting to me, so I decided to investigate.

As many of you probably know, internet pictures of Chinese watches be awfully deceiving, so I was a bit apprehensive. I searched high and low for a specific Chinese company that makes Bliger…but did not get anywhere. Against my better judgment (which seems to happen a lot with watches, flashlights, knives etc…lol), I decided to pull the trigger on this GMT watch (As mentioned earlier…I also purchased a second Bliger, a Sub homage, which I will review at a later date). I bought this off of ebay for such a great deal, that I had very little risk.

The Bliger GMT Master II homage I received has a Chinese automatic movement, and is typically priced between $90-$150 for buy-it-now listings on the bay, on Amazon and other places. Like many Chinese brands, you should be able to get one for much less on traditional ebay auctions…but only if you are very patient. I paid $26 + $10 shipping…$36 total…VERY inexpensive. Don’t hate me…

CASE/CROWN/LUGS: The 316L (the ‘L’ designates low-carbon content) Stainless Steel case is listed at 43mm. The overall height is 14mm high (15mm including cyclops). The watch is definitely in the sweet spot of my size-range (I prefer a 43m). Yes…it is a big watch, folks…but seems to work just fine for my 7-3/4” wrist. Lug-to-lug is 52mm. The top of the case is brushed, and the sides are polished. The crown protector extends a bit at the 3 O’clock side of the watch, covering just over 1/2 of the crown. The large, screw-down crown is well-knurled and very easy to grasp. It is polished on the end and has no logo.

^ Side views ^

CASEBACK: The screw-down SS case-back requires a Rolex-style tool to remove. I used the rubber-ball method to remove the back with ease. A single, black o-ring seal protects the movement from outside elements. Bliger gives this watch a depth rating of only 3ATM. Therefore, I cannot recommend this watch for diving.

BRACELET/CLASP: The solid link, 21mm Stainless Steel oyster-style bracelet has screw-pins on five links for easy adjustability. It is fitted with a double-locking deployment clasp which appears to be well made. There is also a nice micro-adjuster underneath the clasp. The end links are also solid, which is a pretty nice feature at this price. All center sections and outside sections are brushed, and the sides of the links are polished. BLIGER logos are printed twice on the closure, as well as “Actomatic 1368”. I’m not sure if that is supposed to be some brand name for their watches/bracelets…or if they misspelled Automatic. My money is on the latter…

^ Bliger clasp logos, along with “Actomatic 1368” text…lol. At least it is not on the dial ^

^ Micro-adjustment on back of clasp ^

DIAL/HANDS/INDICES/FUNCTIONS: BLIGER logo up top, and GMT AUTOMATIC/58 text down low. I am not sure what the 58 is supposed to stand for. The black dial has traditional GMT II, Rolex-style indices. They consist of an inverted triangle at 12 O’clock, rectangles at 6 and 9, and circles on the remaining hours. Each indice is raised with a silver edge, and a white, lumed center. A date window at 3 O’clock takes the place of the missing indice, and is easily distinguishable with the date-magnifier window. The date wheel is white, and has black Arabic numerals. The hour-hand is a typical Mercedes-style, with the minute hand a much longer sword-style, and the second hand, more of a lollipop/pointer with a small lollipop counter-balance on the opposite end. The fourth hand is the GMT, and a few mm shorter that Rolex’s version, but looks almost identical…with a red shaft, and silver lined triangle pointer. There are nicely lumed indices and hands, but the lume itself needs more staying power…but definitely a step above the lume on a typical Chinese timepiece.

^ Blue lumed indices…hour, minute and second hand…green on GMT triangle pointer ^

^ “BLIGER” logo at 12 O’clock, and “GMT AUTOMATIC/58” at 6 O’clock ^

MOVEMENT: Chinese automatic with no markings, but appears to be a DG3804B (appreciate it is someone could confirm this for me). The rotor is audible off the wrist, and slightly audible while on. It has kept very decent time, gaining an average of 15 seconds/day. This movement spins like a friggin’ top…up to about 12+ seconds at a time, which keeps it well-wound.

^ No markings on this movement ^

^ DG3804B? ^

CRYSTAL: The sapphire crystal is flat, and has a cyclops (date-magnifier) at the 3 O’clock position. The crystal does extend above the bezel very slightly, approximately .3mm. There does not appear to be any AR coating.

^ Here’s lookin’ atcha! ^

BEZEL: The aluminum Pespi bezel is half red (06:00-18:00)…and half blue (18:00-06:00). The colors look well done and are a pleasing hue. There is no GITD pip at the traditional, inverted triangle at the top spot, which is consistent with the Rolex version. Large, Arabic numerals are placed at even-numbered hours…and simple dots on the odd hours. The bezel has a gear-tooth style surround, which is sufficiently grippy. The bezel has approximately 72 clicks. The clicks are solid, and there is no rattling or slop. However, the bezel insert spins very slightly, under increased thumb-pressure, when rotating the uni-directional bezel. I don’t think this makes a difference on a 24 hr. watch (vs. diver), but it should have been fastened better.

^ I like it on the wrist. What do you think? ^

PROS:
Pretty accurate automatic movement at +15 sec/day.
Looks almost exactly like it’s Rolex counterpart.
GMT hand independently adjusts, so watch could be used to keep track of up to 3 time-zones.
Movement also hand-winds, and hacks.
Above-average fit and finish.
Protected and grippy screw-down crown.
Bezel clicker has no slop and is uni-directional.
Date function with easy-to-read cyclops.
Substantial size and weight.
Decent, screw-pin bracelet with solid end-links/bracelet links and hidden micro-adjustment.
Flat Sapphire crystal.
Blue lume on hour, minute, second hands and indices. Green lume on GMT hand pointer.
Rotor spins and spins and spins.
Other color combos to choose from.

CONS:
Better quality lume needed.
No box or papers.
Bezel insert rotates slightly under heavy pressure.
3 ATM water resistance.

DIMENSIONS (Actual):
Width including crown: 48.5mm
Case Diameter: 43mm
Lug-to-lug: 52mm
Lug (Bracelet) width: 21mm
Crystal: 32mm
Overall Height (top of crystal to caseback): 14mm (15mm including cyclops)
Weight: 174gms

RATING:
Cost: 5
Looks: 4
Durability: 4
Function: 4
Comfort: 4
Average: 4.2/5

In conclusion, the Bliger GMT Master II homage is a substantial watch with huge bang-for the buck. While there could be some improvements made, it has many nice features that cannot be found on other timepieces at this pricepoint. It offers a great deal of watch for the money. It just looks good, operates adequately…all for a scant $36…delivered (well…that was MY winning bid…YMMV)! Litte risk…solid links…Stainless..GMT…sapphire…Pepsi…nice! I consider this another great deal, and recommend it.

Some weeks ago, in tribute to a half centuary of personal existence, a few time ago, I decided to gift myself a decent quality upgrade to for my little knive collection. Wanted was a pretty well made, really nice looking. medium large folding knive, with a high quality blade steel, that is legal to carry in Germany, wherein by law all types of one handed opening folding knives with blade locking mechanism are not allowed to be carried in general public areas. So I started to watch out the www from east to west and south to north for a folding knife with this tiny bit of something special, that would satisfy my mind and even fits the budget range.

But as it turned out, to find the real thing was much more difficult than expected, and times of vainly searching had been passed, until some lucky day I fortuitously clicked a YouTube video, that finally leads me to the website and store of a 60 years old professional semi-professionally knifemaker, whose name I never heared before, but nevertheless seems to have highly recommendations within the scenes of hunting and fishing, which requirements most of his knives are intentionally made for.

Reinhard Müller started to build fixed blade knives as a young mans hobby in 1979, and after decades of gaining experiences and purchasing professional machinery equipments, he turns his passion to a little one man’s siteline company. For a long time he produces only relative high prized handmade fixed blade custom knives, but due to his success and high demands he went up the next step and extended his product range with a series of semi custom fixed blade knives, of which the single parts are industrial machined by some European ancillary suppliers and get mounted, finished and quality checked at his own workshop. Some years ago he completes his product range with a small series of folding blade models, produced in the same way as the semi custom fixed blades.

After a bit longer introduction for backround informations, it’s time to come up with the show. So here’s the stuff, that I got from this guy.

At first I recived the MSP Liner Lock model with handle scales made of Desert Iron Wood
!!

Overall Length: 7.78” ( 20 cm), Handle Length: 4.53” (11,50 cm), Blade Length: 3.35” ( 8,5 cm ), Blade Thickness: 0.15” (3,8 mm),
Blade Material: CPM-S90V, Blade Style: Plain Edge – Drop Point – Matted Finish -, Handle Thickness: 0.55” (14,0 mm), Handle Material: Desert Iron Wood , Lock Type: Liner Lock, Platine Thickness: 0.06“ ( 1,5 mm ), Weight: 4.96 oz. ( 140,70 g ). Liners, Thumb Disk, Spacers, Blade Stop Pin, Clip & Clip Cover are made of 1.4021 (X20Cr13) AISI 420 Stainless Steel. ( the Liner Lock model seems to be currently out of stock )

With the MSP Liner Lock I got immediately excited by the first look just to went thrilling enthusiastic with the first touch, so it was somehow impossible to resist these burning desires, that came up for a secound wanted model of the MSP folding knife series.

So for the second knife, I choosed the MSP Lock Back model with handle scales made of stabilized Bog Oak Wood.

MSP Lock Back, MSP Liner Lock and a Native style Spidy clone

In my opinion with the MSP ( Müller Super Professional ) knives, althoug they are not quite cheap, you’re getting a big value for the investment.

Currently Reinhard Müller is still doing a regular job as commodity buying agent, and runs a litte online-store , where he sells his knives and an amount of basic materials and precasted single parts for d.i.y. knifemakers. http://www.mueller-messer.de/

Hello guys!
Well, you know, I try to give respect to this big folding knive in my cheese english, but sometime it’s hard! So simply I put a small video with some bla bla bla in italian language
I know, you do not understand italian, so just keep a little trip on video, maybe put a song under the vision and take off my voice
Ladies and gentlemen, here you are the fabulous Ganzo G723!

It’s a frame lock, a solid frame lock, with a single G10 handle, in my case I’ve choose orange color

Take a look at the blade shape, it’s beautiful!

To understand how big it is, just look a little comparison wit a Mora Companion and a famous Sanrenmu 710

Again, now with a Victorinox Hunter.

The comparison between the blades is palpable

And now, the video!
With a little appearance of Ted Bundy and another monster…brrrr

Enjoy it!

Thank you for checking out my latest watch review! In this review, I will be looking at a Stainless Casima Charisma, Model 5114, 42mm, Day/Date/24 hour quartz watch.

^ Website Pic ^

The BangGood listing picture above features a decent looking product…a product that looks somewhat suspiciously like an Omega Speedmaster…not necessarily a bad thing.

FYI…this ‘Mushroom Brand’ (one of several brands that seem to spring up everywhere) Casima 5114 watch is available in two versions…with a Stainless Steel bracelet, or a black leather strap. I will be reviewing the SS band version. I received this watch gratis from BangGood for review.

^ A few of my own pics from lightbox ^

From what I can determine, the company that owns Casima Watches is the Shenzhen IDS Watch Co., Ltd. . This is their Alibaba site, which was the only website I could find for them.

The specs as they appeared, verbatim, from the BangGood Listing :

KronoReview:

First…the unboxing:

^ Box with my new favorite EDC knife, the Ganzo G753 Axis-Lock folder. ^

^ The Casima came in a very well padded/bubble-wrap envelope, with outer cardboard box wrapped around a nice inner retail box. It was VERY well protected. ^

CASE/CROWN/CASEBACK/LUGS: The Stainless Steel case is 42.25mm, and the overall height is 10.5mm high, a pretty comfortable size for me (I have a 7-3/4” wrist). The top and sides of the case are polished. The crown is properly knurled and easily gripped, and sports their embossed logo on the side. The pusher at 2 O’clock controls the day of the week, and the pusher at 4 O’clock controls the date. The screw-down case-back requires a standard 3-point or 2-point adjustable tool for removal. There was a singe black o-ring seal underneath. The depth rating is 10 ATM, but I would probably avoid anything beyond hand-washing with this watch.

BRACELET/CLASP: The solid link, 20mm Stainless Steel oyster-style bracelet has eight removable links for easy adjustability. The end links are also solid. The center links of the bracelet are brushed, and outside sections are polished. The double push-button, locking deployment clasp is of a decent quality, has 3 positions for micro-adjustment, and has the Casima logos present.

^ You can see a mark on the buckle. I believe this was adhesive residue from removal of the protective tape. This residue was easily removed using a Magic Eraser. ^

^ Adhesive removed. ^

DIAL/HANDS/INDICES/FUNCTIONS: The black dial has raised, baton indices fashioned in angled chrome. There are also vertical lines running down the entire dial. There is no traditional date-window. Instead, there is a date sub-dial at 6 O-clock. A day sub-dial is at 3 O’clock, and a 24 hour clock sub-dial is at 9 O’clock. There are no numeric markers on the indices, and there are seconds and micro-seconds hash-marks between the indices. The Hour, Minute and Second hands are sword-style designs that are also chrome in color. Lume exists only on the Hour and Minute hands…and not very much of it. There is an internal, black tachymeter ring with white numbers & letters. I found that it was a challenge at times to quickly tell the time, and it was definitely a challenge telling the day and date due to the small numbers on the sub-dials.

MOVEMENT: Japanese Epson VX9JE quartz, no-jewel, quartz movement. I verified this through removal of caseback and internal inspection.

CRYSTAL: The Casima 5114 crystal is flat, and purported to be “Hardlex”. I am unable to verify this. The crystal does extend above the bezel ever-so-slightly, perhaps .2mm, and I am confident in saying that there is no anti-reflective coating.

*+BEZEL+: *Very standard, non-prominent, non-rotatable, un-numbered, polished Stainless Steel bezel.

PROS:
Japanese Epson (Seiko Company) VX9JE quartz movement.
Sony battery.
10 ATM water resistance.
Styled like an Omega Speedy.
Day/Date/24 hr. displays on sub-dials.
Tachymeter ring.
Attractive fit and finish.
6 point, screw-down Stainless Steel caseback.
Moderate-feeling Stainless bracelet with solid end-links/bracelet links. 8 removable sizing links.
Double pushbutton, locking deployment clasp.
Flat ‘Hardlex’ crystal.
Lume on hour and minute hands.
Retail box.
Choice between leather strap and Stainless Steel bracelet.

CONS:
Legibility, especially of the sub-dials.
Insufficient lume on hands, and no lume whatsoever on dial.
Cheap sounding bracelet, although it wears and looks fine.
Styled like a chronometer, but no chronometer function.

ACTUAL DIMENSIONS:
Width (including crown): 45mm
Case Diameter: 42.25mm
Lug to lug: 51.5mm
Bracelet width: 22mm
Crystal: 38.5mm
Overall Height (top of crystal to bottom of caseback): 10.5mm
Weight: 136gms
Battery size: SR927SW

RATING:
Cost: 4
Looks: 3
Durability: 4
Function: 3
Comfort: 4
Average: 3.6/5

In conclusion, the Casima Charisma 5114 is an OK looker, and a decent feeling watch. This is the first Casima watch I have used, and it seems to have reasonable functionality for it’s cost. The utilization of a Japanese quartz movement, paired with usable (if somewhat challenging) functions, makes this watch a consideration, especially for the low cost. Overall, a reasonable watch for a reasonable price.

So i know how crazy everyone is about the Ganzo knives, and I wanted to take the chance to do a quick review on the Fura S35VN knives at gearbest.
Plus I just set up a imgur account to try to fix the damage that the other company (the one whose name we must not say) has done. Next step is to start transferring hundreds upon hundred of pictures over to imgur.

Fura S35vn Knives @ Gearbest
http://bit.ly/2usVFg6 (Affiliate link)

So I saw these S35vn knives that Fura is making and at first thought… it’s a trap! Then I started to think about the quality that Ganzo is putting out, and how nice the steel is on the Y-start D2 knives is for the money and decided I had to be the guinea pig and try these out. Ended up at my door in about 12 days and was packaged in a small tin case with a plastic viewing window.

This thing is a small knife! But also very heavy for such a small thing. My scale is missing… probably stolen by drug dealers, so I can’t say exactly what the weight is on this.

Construction:

This knife is as simple as it gets. No pocket clip. No lanyard hole, no keychain ring. Just a knife. The knife uses a double ball/detent system to hold the blade in the closed and open position. There is a small lockbar milled into the frame that contains the ball and provides tension for the knife. It opens with a pill shaped thumbhole and has a cutout so that you can reach into it. There is a stop pin on the blade that connect with the frame to keep the knife from over extending. It is an open pillar construction with 2 torx screws holding the knife together, one of them being the pivot.

My Youtube Review:

Performance:

So I pulled this little gem out of the box and flipped it open and it was nice and smooth. It looks like 1 phosphor bronze washer and one nylon. I was unable to shake the knife open no matter how hard I tried. The ball and detent held it closed with ridiculous amounts of shaking. I took the knife to some carboard and it instantly bound up! Panic envelopes me that this was going to be a disaster. I took the knife to my arm hair and it shaved the hair off easily. Took it to paper and it cut. Then I brought it to a receipt and is did not cut that. I looked at the knife closely and noticed that the bevel was extremely steep. I put it against a flat surface and the angle was imposing. That explains the poor performance with cardboard. The steep bevel was binding up the cardboard and not allowing the sharp edge to slice.

So after some whining, and more whining I decided to reprofile the edge. This thing is s35vn steel (allegedly) and it would benefit from a nice thinned out edge. So I busted out the DMT and Eze-lap diamond stones and started with the extra coarse. I easily took about 10 degree away from the bevel angle over the course of about 2 hours. Slowly and methodically checking it with a sharpie marker as I went. I can say that this is a very tough steel! This was not an easy task at all! So after about so hours my new established angle finally met up with the edge and created a new apex. It took a wicked wire edge! I then quickly (about 20 minutes) worked my way through my fine and ultra fine diamond stones to refine the edge. Having the shallower bevel made it a little easier to sharpen as the bevel was now big enough to rest firmly on the stone as I sharpened. After the ultra-fine I took the knife to my arm and had a nice bald spot to show for it! I then pulled out the strop and went from black compound, to green, and then finally with a .5 micron diamond paste. It now had a nice fine edge with no burr, and grabbed at my nail like my best knives.

I was happy!

I took it to cardboard and the performance difference was huge! I was able to cut through entire 12-20” piece of thick corrugated coardboard without it binding. I took it to paper and it sliced nicely. It was still a little shy around receipt paper though, but I think that is due to their still being alot of meat around the edge that was tearing the receipt paper rather than letting the edge cut.

So I cut about 40-50 linear feet of cardboard and the edge was just as good as when I started. I did not I did have one spot on the edge where I had a rough spot, but I think it was due to my sharpening skills more than anything. When I tried to slice cut I noticed it, but did not notice it with push cuts.

I’ve done quite a bit of edge testing with knives and 40-50 feet of cardboard will dull all but the best of steels. The only steels I’ve had go over 50 feet of cardboard are D2, CTS-XHP, VG10 (spyderco), s35vn, 690co. So I am satisfied to say that my results for Fura’s S35VN are in line with my previous tests. Most cheaper steels like 440C and 8CR13MOV will only do about 30-50 feet of cardboard before they lose that edge.

My Opinions:

This is a tough knife to review. There are no S35VN knives on the market under $60. This little guy comes in around $25. Firstly I will say this knife would be greatly improved with a lanyard ring. A small paracord lanyard would really make this more comfortable to hold onto. I really don’t think the handle is titanium. It just feels too heavy. I suppose that it is stainless steel with a titanium coating.

I’ve dealt with this double detent locking system with some SRM knives. You have to be super careful because one little smack and it can close on you. So treat this knife accordingly. But it does hold the blade firmly in place while the knife is closed.

It opens smoothly and you can open and close it with one hand.

Aside from cutting cardboard I also did some meal prep for a few days, and used it to cut zip ties and let it spend a little time in the garden pruning tomato plants. It cuts nicely and has maintained a good edge for me. I am happy with the quality of the steel and heat treat.

I think if Fura expands on this line and makes some larger knives with a frame/liner lock they would be wildly successful if they can keep the price low.
These Fura Knives ride nicely in the watch pocket of your jeans by the way. They also drop easily into the console of a car and other small places like your pen drawer at your work desk.

This knife is in no way, shape, or form going to compete with a small spyderco. But for half the price they are not a bad little investment. That is with the huge caveat that if you want to use it for fine tasks your going to have to spend some time reprofiling that edge and thinning it out.

Would I buy this again?

Yes. This is a handy little knife to stash away, and I’m happy with the cutting performance after I reprofiled the edge.

Horrible BLF confession. I love off brand power banks. Especially inexpensive power banks. Don’t get me wrong… I own a couple Anker power banks and I’m super happy with them. But I just cringe at the idea of bringing a $60 power bank backpacking or to the beach. I cringe at the idea of leaving it in less than ideal conditions that will degrade the 18650 cells inside. So I wanted a couple “throw away” power banks for those sticky situations and enter the Romoss Sense 6

Review:

There are plenty of pictures and video of this unit being torn down and it is no secret that it contains 8×2500mah chinese made cells, which totals to the advertised 20,000mah specs. As many of us know, this is not truly accurate because the 3.7V 18650 cells need to be boosted to 5.0v required for USB. The conversion is only about 75-90% efficient which really leaves us with about 14-15,000 real mah. This particular model is claims to be capable of outputting 3A over two separate usb outputs.

The labeling is pretty straight forward. One lightning bolt for the 1a channel and 2 lightning bolt for the 2a channel. My testing I was only above to get around 2.5a while using both channels. I was never able to obtain the full 3a. The Sense 6 can be charged at 2A, but I was never able to get it to accept more than 1.5A. Could this be my cables? sure. But I tried several and got different results with different cables. Pretty typical as USB cables degrade quickly.

The Sense 6 is pretty clearly labeled with the specs on the back and the LED panel is easy to say. It tells you the remaining % of charge. There is also a small on/off button on the side.

My Youtube Review:

Final Thoughts:
To me the sense 6 is terrific. it brings a real 20k mah power bank into the affordable for everyone range. The $25 price is very enticing and for that price I can live with the shortcomings, which really are not that bad. The question here is whether or not the inclusion of inexpensive chinese cells to save money is actually worth it? In this case I think it is. This is a power bank that you can use and abuse and will not be sorry if you destroy it. It is enough to charger your average phone 4-5 times on one charge. These chinese cells are going to degrade a little quicker, but even cheap chinese cells are capable of reliable providing a sustained 2a output.

if I need something to charge at exactly 2a I’m going to pull out my Anker power banks… no doubt. but if I’m lazily charging a few phones on the beach, in the sand and the sun with water close by… I can guarantee my Anker’s will be safe at home.

With a price difference of about 30-40 dollar between the Sense 6 and other products like Anker, I can live the difference in performance.

This sense 6 has been used daily now for several months. My wife keeps it in her purse, and is constantly charging her and her co-workers phones all night long. She also uses it to charge her e-cig. This thing is essentially in use 16-20 hours a day over the last few months. Over the course of her 8 hours shift she typically will bring this home with about 40% charge left, and it takes around 6-8 hours to fully charge it back up. It’s pretty impressive considering the amount of use she puts it through. We have several Anker power banks, and a few of the Xiaomi Mi power banks and this is the one she chooses to bring with her.

We ended up liking this one so much that we ordered 2 more for our upcoming vacation. I’ll try to update this posting in a few months and see how this is holding up after a few more months of non-stop use.

Hey guys!
Let me show you this nice blade, the Ganzo G7522 Bk (black handle), a very well made knife!
Let’s start the show!
But first I must say “thank you” to Gearbest.com that send me the knife for an honest review. This is the really first knife I have not to pay for, so I am very proud of it I will try to be objective.

Do you see the frame lock disappear into the G10 handle? VERY NICE!!!!

With a “traditional” frame lock

The family

Sincerely, I can recommend this knife. Solid, light, bad, aesthetically beautiful, functional. The Ganzo G7522 bk is also a great choice as edc. You can’t go wrong with it!

And finally, as always, the video!
In italian language as usual, but with a good country song and an attempt to catch a chicken…and many horses!
So, even if you do not speak/understand Italian but like country music and horses, take a look at it, please!

I received the Nitecore NEB10 for the review from Nitecore.

I use several EDC pouch/bags, both in my work and in my free time.
The NEB10 is a 6 liters EDC bag, that can be carried over the shoulder and secured to the body with a second belt. It is available in black and grey, I got the grey version.
The NEB10 is made of 1050D Nylon, with the front part with the MOLLE system in rubber.

Here is the front part with MOLLE system.

The MOLLE attachment points are also on the sides.
The zippers run fine and are equipped with practical D-rings.

The NEB10 has 4 compartments.
The main (40×20×7 cm)runs along the whole length of the bag, and has 2 drain holes (a Nitecore Thumb is the light in the pic)

On one side there’s hook and loop system (Velcro for attaching other bags and accessories) and on the other there are some elastic loops.

The 2 front pockets (16×16×2 cm) are symmetric and have a mesh divider

On the back there’s a big mesh, with a piece of Velcro for “closing” with the main body of the bag.

Beside the main strap, which runs over your shoulder, there is a smaller secondary one, that prevents the bag from bouncing around when you are moving. You have several attachment points for that belt.

Here’s strapped on my back

On the main strap there is a not removable MOLLE Pad

When I turn it around making it end up on my torso, accessing the pockets is easy.

My thoughts
The materials used for this bag are fine. The zippers run fine and the bag has some waterproof capability.
Compared to other bags, the tissue is a lighter and it makes the whole bag lighter without making it weaker.
While using the bag as it is, I found the lack of zip pouches and other (smaller) elastic bands for retaining smaller items. For my uses, a bag needs to have more dividers, more elastic bands and zip meshes (you can do that by adding your desired pouches, using the hook and loop pouches and organizers); and a handle.
I would have liked to be able to use the MOLLE system on the bag to attach flashlight and other pouches, however the cut on the rubber are too tight for most of my pouches. You need to use pouches or accessories with tight straps, or use classic MOLLE clips.

A friend lend me his Nitecore NDP20 (a EDC Organizer), here are some of my thoughts on it.
The NDP20 is a compact EDC organizer with 2 compartments. There are several other EDC organizers, that differ mainly for the size of the front compartment and the correspondent presence or absent of a front Velcro layer.

The NDP20 can be carried using the provided strap, or the handle, or integrated in your system using the MOLLE attachments, with the provided MOLLE straps.

If you carry it with the MOLLE system, or within a bag, the strap can be removed and the 2 big D-ring are left free for carrying more stuff.

The Zippers are equipped with D-ring pullers

The 2 compartments are easily accessible because the zippers extend all the way. In each compartment there are elastic loops.
In the small compartment (15×15×2 cm) there’s a small d-ring and a keychain carrier. (velcro for attaching other bags and accessories)

In the bigger one (22×16×4 cm) there is a second compartment and some Velcro for Hook and Loop capability

Even when carried, you can access the whole contempt of the bag without taking it off of your shoulder.

Here’s the NDP20 with some EDC content: a knife, a multitool, a pen, a 2.5” Hard Drive, a Zippo lighter.


.
.
My thoughts
The NDP20 is a well made bag, and I would like it to have more small elastic bands, because, as you can see in the pic, they tend to keep in place firmly only large pieces of EDC equipment, like big multi tools or large knives.

Thanks to: AntoLed for the camera help.

DMM Aneng AN8008



This is a cheap DMM with all common function.



It included the DMM, two pair of probes and a manual.




The standard probes has removable tip covers.



The probes are rated for 10A, I would not trust that but use some more solid wire for 10A range.



The other set of probes fells rather low quality, but has some nice functions. They consist of two wires with threads at both ends and a couple of different tips that can be mounted in each end. It is slow to use, but very flexible.



Here are all the different tips.





The body of the DMM feels solid, the plastic is rather smooth, i.e. the DMM can easily slide on a surface. The tilting bale is rather flimsy and do not give enough support for pressing buttons and turning the range switch.






Display



The above picture shows all the segments on the display.
Notice how u and m symbols are at multiple locations, making it possible to show them just before the unit.
The °F, °C, MIN, MAX and delta indicators are not used on this meter.



Typical display during usage, it will show the number and what measurement is selected.



Functions



Buttons:

• Range (Blue): Will disable auto range and change range, hold down to activate background light.
  
• Sel/Hold (Yellow): Select the ranges printed with yellow, hold down to freeze the display reading.
  

• Off: Meter is turned off
  
• V % Hz: Show voltage, using the yellow button will cycle between VDC, VAC, freq. and duty cycle.

• Hz: Frequency and duty cycle.
  
• A mA: Current AC and DC.
  
• uA: Current AC and DC.
  
• Square: Frequency out, use the yellow button to select from 50Hz to 5000Hz
  

• A mA: A very low burden voltage mA range and a 10A that cannot really handle 10A.
  
• CON: The common terminal for all ranges.
  
• xxx: All other ranges, including uA. It is always problematic when a current range shares connector with a voltage range, if the switch is in the wrong position the (hard to replace) fuse will blow (at least). This will only affect current, voltage will still work.
  

• Volt and frequency
  
  
  
  • AC volt can measure up to about 2kHz (RMS will not work at the frequency).
    
  • At 1Vrms input frequency range is from 1Hz to 3MHz

  • mV range is high input impedance for both DC and AC
    
  • Frequency input needs about 180mV to work at 1kHz.
    
  • Frequency counter and duty cycle works without zero crossing in Hz range.
    
  
  
• Current
  
  
  
  • 10A range is badly calibrated at high current.
    
  • 10A range will change some percent at 5-10A current due to heating.
    
  • 10A range will give an audible alarm when current is above 10A (uA will not).
    
  
  
• Ohm, continuity, diode and capacity
  
  
  
  • Ohm voltage is 1V open and 0.42mA shorted

  • Continuity is 1V open and 0.42mA shorted
    
  • Diode voltage is 3.2V with display of up to 3.000V with 0.2mA, maximum current is 1.8mA shorted
    
  • 70000uF takes about 8 seconds to measure.
    
  
  
• Miscellaneous
  
  
  
  • A beeper will sound shortly before the meter turns itself off
    
  • Current consumption of meter is 1.6mA (7.5mA with backlight)

KronoReview:

I have been enamored with the Carnival Tritium watch after seeing it online. Even more so because of the positive response BLF member JohnnyMac had when he bought one some time ago. Well…I finally received one for review. I guess the pictures featuring those delectable Tritium vials were calling my name. Maybe…just maybe because I am a flashaholic and love lumens?

Anyhow, this Carnival M/N 8638G is a field-watch style, and very versatile with casual or semi-formal attire.

The Carnival watch came in a padded/bubble-wrap envelope, wrapped securely and very protected, and sealed inside a styrofoam shipping box. Inside the shipping box was an outer retail box, with a nicer inner-box, sizing tool, warranty card, booklet etc…it really makes you feel as though a quality product awaits inside. So…Is that the case (pun intended)? Let’s see…

CASE/CROWN/CASEBACK/LUGS: The Stainless Steel case measures a width of 40mm (43.5mm w/crown), and the overall height is 12mm high…a good size for this type of watch. Lug-to-lug measurement is 49mm. The nicely curved sides and top of the case have a very workmanlike, brushed finish. The relatively thin, angled bezel is fixed and un-marked, as well as highly polished. The Stainless Steel case extends under the crystal to an attractive, stepped rehaut that butts up to the chapter ring. The pull-out crown is a nice size, properly knurled and easy to manipulate. There is a raised Carnival logo on the side of the polished crown. The screw-down case-back utilizes a standard, six-indention design for a 2 or 3 point removal tool. Upon removal, there is a single black internal O-ring seal between case and back. The watch has a 3ATM water-resistance rating. Therefore, I won’t be using this while swimming, but it has been fine for dish duty.

^ A TON of pics of this watch amongst the Rocky Mountains in beautiful Banff National Park, Canada. Sorry there are so many…I just couldn’t help myself.

BRACELET/CLASP: The solid link, 20mm Stainless Steel bracelet has a modified, oyster-style look. The outside links are brushed on the top/bottom, and polished on the sides. The center links are also brushed, but have a smaller polished end piece on each side. These pieces match well with the polished bezel, providing a nice contrast to the mostly brushed surfaces on the rest of the watch. There are six removable links for adjustment, held together by standard split-pins (split-pin removal tool included). The double-pushbutton, butterfly clasp is nice and secure, and has “Carnival” & “1986” on the middle attachment links, and “Stainless Steel” etched on the inside. The butterfly closure does not allow for micro-adjustment for wrist size, so it might fit a little snug or loose, depending on what you are more comfortable with. Not a huge negative, but could be an annoyance if your wrist size is somewhere in-between.

CRYSTAL/DIAL/HANDS/INDICES: The white dial has traditional field watch looks, with ample, easy-to-read Arabic numbers next to the Tritium indices. Just inward of those numbers are smaller, 24 hr. Arabic numbers, from 13-23. Each indice extends into a notch on the white chapter ring. Each hour indice is marked with a T25 ice-blue Tritium vial, with the exception of an orange trit at 12 O’clock. A day/date window, outlined in black, sits between the 3 O’clock indice and the center of the watch. The white date wheel matches the dial well, with black Arabic numerals and abbreviated day indicator (except, of course, a red Sunday “SUN”). The hour and second hands are a pointed baton/radium style, with ice-blue T25 Tritium vials in the middle. The rectangular paddle-style second hand also has a small ice-blue trit in the center. The Tritium vials are remarkably visible in the dark! I originally thought that I would want much brighter T100 trits on a watch, but I’m beginning to think they might be too bright. With a total of 15 trits, this watch, IMHO, is PLENTY bright! So much so that it freaks my wife out if she wakes up and catches a view of it as I move my hand (I’m quite the restless sleeper). The sapphire crystal is awesome and very scratch resistant. It also has an excellent anti-reflective (AR) coating, and does a phenomenal job of making the crystal disappear when looking directly at the watch. The AR coating, along with the large numbers, makes this a very easy to read, legible watch. If I had to change anything, I would use a different color trit on the hands for increased nighttime legibility.

MOVEMENT:Ronda Powertech (Series 500) 517 1 jewel, analog quartz movement with Hour/Minute/Second and Day/Date functions. “Swiss Parts” is printed on the movement, so I am assuming that they are assembled somewhere outside Switzerland. The watch came equipped with a Renata 571 battery.

PROS:
Tritium, Tritium and more Tritium!
Swiss Parts 1 jewel Ronda quartz movement with Renata battery.
Excellent night-time legibility with the 15 trits on indices and hands.
Top-notch daytime legibility with white dial, large contrasting black Arabic numbers/hands and an excellent crystal.

DIMENSIONS:
Width: 43.5mm (including crown).
Case Diameter: 40mm.
Lug to lug: 49mm.
Bracelet width: 20mm.

Weight: 132gms.

RATING:
Cost: 5
Looks: 5
Durability: 5
Function: 5
Comfort: 4
Average: 4.8/5

CONCLUSION: I like this watch. OK…I REALLY like this watch…maybe even love it. Keep in mind that I am an automatic/mechanical watch kinda guy, so it is a bit surprising to me that I’m so smitten with a quartz watch. This is just such a handsome looking, highly legible, nice feeling timepiece! And I cannot find a decent (nor a crappy one, for that matter) Tritium watch out there that comes remotely close to competing with Carnival at this price point. When I considered all the positive attributes of this watch, it made it easy to proclaim this an exceptional deal. Are you looking for a Tritium watch? Get it!

Thanks,

Hello everyone, today we will see the Ruike Trekker LD43 sent for the occasion by Ruike, whom I thank for the opportunity and trust given to me.





CLICK HERE to go to the official product page on the Ruike's website.


Official features taken from Ruike:

- one-hand operatione and lockable blade
- sandvik 12C27 blade material
- G10 knife handle
- locking mechanism
- tungsten steel breaking cone
- pocket clip design


The packaging and accessories

The Trekker LD43 comes in a sturdy cardboard box, wrapped inside a lighter cardboard sheet which will show the mark and motto of the company.



On the back there are some information about Ruike, where we can see that it is an offshoot of the famous brand Fenix.



Sliding the paper, we can put a hand to the robust box



on which side is pasted a sticker that shows the model name.



then you can open the box by removing the cover upwards.



Once removed everything from the packaging, we should have:

- the Trekker LD43
- sheet for warranty
- the manual in English, Chinese and Spanish



Afterwards, the pages of the manual. You can view it by downloading it from the site Ruike.




The multi-purpose knife

The Trekker LD43 is one of the multipurpose knife from Ruike that aims to meet various needs in a rescue situation but, looking to the components that compose it, is good even to covering up various tasks in outdoor use.
The handle external yellowish/light green, is in G10 and offer an excellent grip.

The steel used is the Sandvik 12C27 (58 ~ 59 HRC). For the uninitiated, is the same which is used in the famous and appreciated Morakniv knives. Although, in this case, hardening heat treatment has generated a stronger steel than the famous Morakniv (who 57 ~ 58 HRC).

The blade of LD43 has a profile tip drop point and the opening is controlled by a thumb stud that allows the opening by using only one hand. The location of this one, and the fact that is placed only on the left side of the blade,  make it comfortable to use only to the right-handed.

On the blade there are the Ruike name,



the model name and the type of steel used.



The touch between the various components is virtually absent and everything flows quite nimbly.



The main blade is the only tool to have the safety lock (liner lock) and it performs very well on his work.



Here is the multi-purpose knife, blade retrieved, in all of its glory.



Just next to the mail blade, there is the serrated blade that is great for cutting fabrics and/or cordage.



After the serrated blade is the saw, that really bite the wood very well.



Ending this side, we have the bottle opener that also work as a flat screwdriver, a wire strippers and fold cables



and a small carabiner to attach the LD43 to backpacks or pants. I turned the multi-purpose knife for convenience. Also notice the presence of the clip. Bottle opener and carabiner share the same magazine.



The tweezers is stuck in the grip



and once extracted, we can note that covers a length of about 2/3 than the multi-purpose closed.



In the tail, on the left from the same side of the clip, there is the tungsten tip that is great to break the panes when needed.



Here it is the tip on the profile.



On the opposite side are the Phillips screwdriver



and awl for wood/needle for leather.



Here are some test with main blade,



with the saw for wood



with the serrated blade/belt-cutters,





with the bottle opener,





with the fold cables,







with the wire strippers,





with the awl,



with the tweezers,



and with the screwdriver.



To be able to bring with us the knife, we can use small removable carabiner for hanging on the pants



or to the backpack.



Alternatively you can use the clip.



I made also a video where I show the key features of the knife (able the english subtitles by the gear). Good vision




Dimensions: dimensions and weight

The LD43 measure 11,50x3x2.30 closed and weighs 203 grams.
Regarding the size of the main tools, the smooth blade is 8 cm long, serrated blade is 7 cm long while the saw is 8.5 cm long.

Here's the picture of how the multi-purpose, when closed, is hosted in a medium sized hand.



Here is the LD43 compared with a big BIC lighter,





compared to a Victorinox Huntsman (91 mm)





and compared to a Leatherman Style PS






Personal considerations

What can I say? This Ruike Trekker LD43 proved to be a good product. Stainless steel 12C27 is very suitable for outdoor use, looking to the presence of a large hacksaw, a good knife and G10 handle that offers a good grip.

Always remaining in blade theme, I found great the one-hand opening. Even if you have to become skilled to make a smooth opening looking that don't help the size of multipurpose.
Very good the blade-lock and the absence of touch between the parties, the only "flaw" is that it isn't optimized for lefties.

The color of the bolsters may or may not like ... some might find it a bit too showy, but personally I like it.

What do you think? Would you buy it?

Hello everyone, today we will see the Nitecore NUP10, NDP20 and NHL02S sent for the occasion from Nitecore, whom I thank for the opportunity and trust given to me.

Where to buy it

The pouches could be purchased from Nitecorestore USA(NUP10, NDP20, NHL02S)


The Pouches

The NUP10 and NDP20 are two of the four daily compact pouches that has available in the Nitecore listed.
They are almost the same product. In fact, the only differences between the various models are the material used for the exterior of the secondary pocket (smaller than the main), velvety material for NUP20/NDP20 and plastic material for NDP10/NUP10, and the size of the secondary  pocket, big almost like the main pocket for NUP10/NUP20 and 1/3 shorter than the main pocket for NDP10/NDP20.
Those with smaller pocket, have in addition a velcro rectangle located above of the secondary pocket opening, where we can attack our patches or, for example, the NHL02S.
The NDP10/NUP10 pouches are available in black or grey, instead the NUP20/NDP20 pouches are available in black or tan.
With each model is included an adjustable strap to carry pouch like a shoulder bag.

After this brief introduction, we will pass to the presentation of products.

I begin by saying that them are been shipped inside a common plastic bag whose task it is to protect them just from dirt.



The NUP10

For the review, it was sent the grey version. The new M.O.L.L.E. attacks in the front is laser cutted. As anticipated, there are 2 pockets and each has a hinge on which there are 2 sliders. To each sliders is attached a small string with non-slip plastic semicircle that helps in opening and closing.



In the rear there are 2 M.O.L.L.E. attacks of old design and sashes (included and removable) to attach the pouch to backpacks or other compatible systems.



Small zoom on the sashes. Note that their velcro closure system.



From the side view, where it shows the size of the 2 pockets, stood out even the plastic D-rings, that are presents on both sides, where you can attach the strap included.



Photo from the top where you can see better the sliders and handle located centrally, at the base of which there are 2 D-rings.



Opening the pockets, you can see the protection for the water. Being the pouches in cordura, they are  waterproof. I personally tried to put the pouch under the strong water jet in my shower for a few seconds and the fabric still wet outside. Inside has not gone even a drop of water.



The NDP20

For the review, it was sent the black coloration. You can see the different size of the secondary pocket and the presence of the velcro strip. As anticipated, products are very similar so therefore I'll leave you only to the photo.













The NHL02S

This NHL02S is an accessory that can be attached with velcro, which allows you to add 2 M.O.L.L.E. compatible compartments, inside or outside of the pouches.
I want to clarify that this accessory is sold separately.

Here's what it looks like from the front.



and the from the back.



Here are the "gores" of 2 compartments enlarged only by the fingers.




The internal compartments

Opening the side pocket, on the exposed side, we will have a small D-rings and a small plastic clasp for keys, 3 medium sized stretch compartments and a pocket. On the inside, however, are only 2 stretch.



The main compartment has a pocket to which are attached 2 compartments. Another pair of these magazines is present on the other side, totally of velcro, on which it is possible to attack even more things.



Models with smaller secondary pocket has the various attacks and magazines prepared in the exactly same way, but obviously has less space available.



The main pocket is identical.



Here's a filling proof.
Inside there I putteded  the Concept1, the LR30, the LA10, the SRT9, a Victorinox, a small Leatherman, a multipurpose Ganzo, a 10000 mAh powerbank and a 18650.
The pouches was closed without any problems.



Note the 18650 attached to velcro with the NHL02S.








The shoulder strap and belt

As mentioned previously, the pouches have included an adjustable strap that allows them to be worn over the shoulder.





Alternatively, you can take advantage of the comfortable reinforced handle. Note how the small NU05 is housed inside the M.O.L.L.E. attacks



The flashlight can be docked also with the handy velcro rectangle whom the NHL02S



or alternatively you can stick to the secondary pocket's velvet.




Dimensions: dimensions and weight

According to official data, the NDP20 measure 22x16x6 cm and weighs around 302 gr empty. The NUP10 measures 22x16x6 cm and weighs about 309 gr.

The NHL02S measures 9x4 cm.

Afterwards, the photos for a dimensional comparison with a Maxpedition Fatty






Personal considerations

Both pouches were spacious and with many compartments.
Cute and not too soldierly colors, the presence of the handle and shoulder strap, the open from above of the 2 pockets, be a viable choice for an urban use.
The fabric waterproof and abrasion resistance, given by cordura, are further steps in its favor and make these pouches great allied to an everydays EDC.

Assemblies and the seams are very good and I have not encountered glitches or problems using. If I must be niggling, I saw that occasionally the sliders budge in the corners due to the waterproof seam.

The only improvement to be made concerns the shoulder strap because, with civilian and light clothes as the summer's, tends to rub and be slightly aggressive.

About the NHL02, I can say that it is a useful accessory. It's a sin that must be purchased separately.

What do you think about? Should you buy it?

DMM UNI-T UT210E



This is a cheap clamp meter with DMM function.



It included the DMM, a pair of probes, a pouch and a manual (Both a English and a Chinese version).




The probes has removable tip covers.



The probes are rated for 10A, but it is not important for a clamp meter.












Display



The above picture shows all the segments on the display.
The circle with the arrow indicates auto power off, holding down the SELECT button during power on will disable that.



Typical display during usage, it will show the number and what measurement is selected.



When using the NCV function the display will show a number of -, depending on the electric field. This can usual be used to see if a mains outlet or cable is powered or trace a cable that is just under the wall. This function is always a guideline and not a 100% confirmation of voltage or no voltage.



Functions



Buttons:

• Select/VFC (Blue): Will select secondary functions, holding down the button will enable a low pass filter for AC measurement (VFC).
  
• Zero: Save the current measurement and show the following measurements relative to that value (Very important for DC clamps).
  
• Hold (Yellow): Freeze the display, hold down to turn background light on.

DMM Fluke 17B+



This is a Fluke DMM designed to be sold in China, i.e. I doubt any authorized Fluke dealer in the EU/USA will have it, but due to all the Chinese shops selling directly to EU/USA it is very easy to buy and considerable cheaper than a regular Fluke DMM.

Vapcell Internal Resistance Tester YR1030



This is a meter designed to measure internal resistance in batteries.



I got the meter in a cardboard box with specifications on the back.



The box contained the meter, 4 terminal probes and a manual.



The meter is in a standard box, i.e. not a box manufactured for the meter.




There are two connectors, a micro usb for charging the internal battery and a usb for probe connections.
Generally I do not like using usb connectors anything but usb connections, but in this case I do like it, because it makes it very easy if I want to make my own probes. The labels above the usb connector is signal names for the connections.



The probe looks home build, a usb connector with shrink wrap around.



The other end is two pogo pins in aluminium tubes with shring wrap around.
This means I can easily make new probes if I damage the supplied ones.
The dual pogo pins means that it uses true 4 terminal measurement, there is no errors from contact or cable resistance.



The display shows the battery status, resistance and voltage.
Both voltage and resistance can be in manual or auto range.



There is a couple of buttons:
Power is used to turn on/off the device.
Hold/Zero is used to freeze the ohm reading or zero the ohm reading
Range R is used for manual range select on ohms (20m, 200m, 2, 20, 200, auto).
Range U is used for manual range select for volts (2V, 20V, 28V, Auto).



In addition to this Power can be used to activate the menu system. Here Power is the enter key, Hold is the escape key and the two range buttons are up/down.
In these menus a grading system can be setup, this will make it easy to sort batteries according to voltage and internal resistance in 3 bins. It is also possible to calibrate the meter and set some preferences.



Measurements



Due to the way the meter works it do not need a battery to measure resistance, but can be used as a general milliohm meter.
Here I am testing on some resistors and comparing to a very precise meter.
The precision is very good.



The same with voltage, again the precision is very good.



The meter is using a 1000Hz sinus for measuring the resistance

The meter uses 1uA when off and 60mA when on without background light.



Tear down



I had to remove four screws to open it.

















Conclusion

I like this meter, it is very useful for a lot of stuff, not only batteries. It can measure the resistance in a switch, a tail spring, a atomizer and a lot of other stuff.
When used to measure resistance it will give same value as an ordinary DMM except for much better resolution at low values. On batteries the value cannot be compared to the values chargers measures, but usual the datasheet value is measured this way.



Notes

I got the meter from Vapcell.

As reference I used my Keithley DMM7510, it can do 4 terminal ohm measurement.

Internal impedance/resistance of batteries

A couple of weeks ago I was shipped a Fluke 365 Digital Clamp Multimeter from Fluke Corporation.

I was asked to simple use it however I wanted to. I could take it to work and use it there or just keep it at home and use it only when needed. Or I could do both and I chose both.

I have used it for something almost every day since it arrived.

I asked the representative if he would like an all-out testing and review or just casual use review. He stated very matter of fact “Tell me what out think of it, how you feel about the meter.”

I decided that I would do a brief review with the Specs some video footage (don’t worry not close to the long drawn out video like the 362 and the power supply). I have started getting some modern video gear and editing software so this one just shows some uses and showcases some of the features.

The Fluke 365:

Features and benefits

200 A AC and DC current measurement with detachable jaw

600 VAC and DC voltage measurement

Detachable jaw makes accessing wires and viewing the display easier

Built in flashlight/torch allows for easy illumination and identification of wires

CAT III 600 V

Compact design fits in your hand and can be used while wearing protective equipment

State of the art signal processing allows for use in noisy electrical environments while providing stable readings

Large, easy to read, backlight display automatically sets the correct measurement range so you do not need to change switch positions while taking a measurement

Three-year warranty

Soft carrying case

It also comes with:

Coated instruction card

Safety information sheet

Soft carrying case

TL75 test leads

Magnetic hanging strap

Five AA Alkaline batteries

The 365 kind of falls into a mid-level meter among the very large line of Fluke meters. The average price seems to be around $230.00. This is not a budget meter it is however a meter that may well last you until retirement.

I have known people to have Fluke meters for 20 or more years. They are just that well made. Fluke does not accept quality issues of any kind.

The meter is compact and light. Simple to use with auto ranging and the clamp of course. I almost forgot to mention…. The clamp is removable… You have about 3 feet of wire connecting the clamp to the body of the meter.  I love this feature.

In very cramped spaces it makes life so much easier. If you have ever had to repair industrial machinery then you can appreciate this feature very much.

Removing it does not seem to affect the accuracy at all.

I have used several types and styles of clamp meters but this is the first one that it makes my job easier and much of the time more efficient.

I can without hesitation recommend this meter to anyone that is looking for a reliable, accurate, light weight detachable clamp for just a touch over $200.00…. Did I also mention it is a Fluke.

I hope you enjoy the video below. I tried to make it long enough to allow you to see the 365’s features but not so long that it became a motion picture.

It has been my pleasure to have been given the opportunity to review this meter.

Hello everyone, today I'm reviewing the RuikeTrekker LD51-B sent me for the occasion by Ruike, whom I thank for the opportunity and trust given to me.



CLICK HERE to go to the official product page on the Ruike website.


Ruike official features:

- one-hand operatione and lockable blade
- sandvik 12C27 blade material
- G10 knife handle
- locking mechanism
- tungsten steel breaking cone
- pocket clip design


The packaging and accessories

The Trekker LD51-B comes in a sturdy cardboard box where, in the front, is marked the name and the motto of the company



and in the back there are more information about Ruike. As you can understand, it is currently part of the famous brand Fenix.



On one side is attached a sticker that shows the model name and the color of the grips.



Opened the box, we find the multipurpose stayed at a specially shaped compartment.



Once removed everything from the packaging, we should have:

- the Trekker LD51-B
- warranty's sheets
- the manual in English, Chinese and Spanish



Here, the pages on manual that you can download or view from the Ruike website.
N.B.The manual depicts multiple models from Ruike, the one pictured on the second page is LD61, the best equipped of the brand.




The utility knife

The Trekker LD51-B is among the most complete Ruike multipurpose knifes and aims to be a valuable adventure's companion. Thanks to its numerous accessories, it is useful to perform various tasks in outdoor use and is reliable even for small home jobs and not.

As with the other models, the Sandvik stainless steel used is 12C27 (~ 59 58 HRC), steel that is used in the famous Morakniv knives that are well suited for outdoor use.
As for steel, also grips are in the same material as the other instruments of the House (G10) but in this case, are in the black coloration. For the uninitiated the G10 is famous for offering excellent grip.

Let's go to see it in detail.

First G10 grip.



One of the two sides packed with accessories. Will open both to the left and to the right.



The other side with the accessories... the nay (corkscrew).



Second G10 grip, smaller than the other due to the compartment for the corkscrew. On this face there is also the practical clip.



On the bottom is inevitable the small tungsten glass breaker.



All the fittings are tight enough to scroll smoothly and don't have game between movements.



The blade of the LD51-B, as the LD43 reviewed above, has a profile tip drop point and the opening is controlled by a thumb stud which allows you to use, unfortunately, the only right hand.
To follow the view of the groove in the grip that facilitates movement on the thumb stud.







One of the two sides of the blade shows the name of the brand



While on the other there is the model name



and the type of steel used.



The main blade is the only instrument to be equipped with a security lock (liner lock). The block is reliable and the PIN has no obvious games.



There is also a small clamp with wire cutters, lever to allow the automatic re-opening,





small philips screwdriver,



jig saw for wood



scissors with lever to allow the automatic re-opening,





wood awl/needle for leather by adding wires peeler and a key called spoke wrench you need to unscrew the bolts of bicycle spokes



belt cutter with a small 3 mm flat screwdriver at its end,



bottle opener with another flat screwdriver, this time of 6, 5 mm, another wire peeler and two wire ply



and, to finish this side, a small accessory that, when extracted, allows you to attach a strap, a lanyard or carabiner.



At the opposite side, to end all accessories listed above, there is the corkscrew



While, hidden in the handle, there's the tweezer



Once extracted



proves to be long approximately two thirds against the entire body of the LD51-B.



Here are some tests with some of these tools.
The main blade,

the saw



scissors,





The awl,



the small curved blade for cordage,





the wire cutters pliers,



The awl, wire peeler



eyelets to bend the cables,







spoke wrench,



the tweezers,



the philips screwdriver,



the pliers,



the other screwdriver,



and finally here is the LD51-B attached to a backpack through a small carabiner (not included) and its clip.






Dimensions: dimensions and weight

The LD51-B measure 11,50x2,8x2,6 cm when closed (regardless of the clip and the tungsten tip) and weighs 264 gr.
Regarding the size of the main tools, the smooth blade is 8 cm long while the saw is 8.5 cm long.

Comparison with the dimensional LD43 Ruikeand Victorinox Huntsman.



The two Ruike side by side have the same size



but they differ in height saw the largest number of instruments fitted on LD51-B.



Both the main blade that hacksaw also have the same shape and size in both models.





Scissors, by comparison with that of Victorinox, is slightly more generous.




Personal considerations

Even this Ruike Trekker LD51-B turned out to live up to expectations. The stainless steel used is the 12C27, which lends itself to be used for such instruments. Unlike the model previously tried, this proved to be suitable for a range of uses slightly higher while remaining a small product. Does not change the feeling of having a quality product in your hands, given from the excellent materials.

Compared to LD43, weight and thickness are increased slightly and this has slightly affected this model. I have a medium sized hand and I felt holding limit while my colleague, who has a bigger hand, found himself well. But, in live use, this "disadvantage" has't been feeled.

All instruments are easy to open, all accessories sharped (sharp factory direct) and overall this Ruike performs extremely well the work for which it is intended.
The main blade is also a simple but highly reliable security system that locks the blade.

As in the previous model I haven't serious flaws to report. The only negative thing is that is not optimized for lefties, since the thumb stud you can operate only with your right thumb.
Finally, I say it was a stroke of genius put the small removable ring for lanyard or carabiner. It allows us to expand at will the possibilities for multipurpose transport.

What do you think about it? Should you buy it?

DMM Aneng AN860B+



This is a cheap DMM with all common function.



It included the DMM, a pair of probes and a manual (Where some specifications was missing).




The probes has removable tip covers.



The probes are rated for 10A, I would not trust that but use some more solid wire for 20A range.




The thermocoupler is a cheap construction rated for max. 400° 0.75% ±2.5°±C






When using the tilting bale the meter is nearly stable enough to turn the switch and push the buttons (If placed on a non-slip surface it will probably be stable enough).



Meter without rubber sleeve, battery can be replaced without removing this sleeve.

• 10A: High current, it can only withstand 10+ ampere for a short time (Fuse is 10A).
  
• mAuA: The lower current ranges, the selector switch will change between two different shunts (Fuse is 600mA).
  
• CON: The common terminal for all ranges.
  
• xxx: All other ranges, including external current clamp.
  

• Volt and frequency
  
  
  
  • Frequency counter and duty cycle can only be selected in AC ranges.
    
  • Frequency input do requires a zero crossing.
    
  • Frequency input requires about 0.02Vrms before it works.
    
  • Max/min needs about 350ms to capture a voltage.
    
  • At 0.1Vrms input frequency range is from 0.9Hz to 4MHz
    
  • At 1Vrms input frequency range is from 1Hz to 49MHz
    
  • AC volt can measure up to about 2kHz, true RMS will not work at this frequency
    
  • VFC only works in 600.0 and 600 volt mode and reduces bandwidth to about 800Hz
    
  • Input impedance is 10-11Mohm on DC and AC
    
  • Input impendance is high on mV DC range.
    
  
  
• Current
  
  
  
  • Frequency counter and duty cycle can only be selected in AC ranges.
    
  • 10A range has audible alarm when current is 10A or above.
    
  
  
• Ohm, Continuity, diode and capacity
  
  
  
  • Ohm is 0.97V open and 0.30mA shorted
    
  • Continuity is fast (About 20ms).
    
  • Continuity beeps when resistance is below 50ohm
    
  • Continuity is 1.01V open and 0.30mA shorted
    
  • Diode range uses 3.2V, max. display is 3.000V at 0.09mA, max. current is 1.21mA shorted
    
  • 70000uF takes about 10 seconds to measure.
    
  
  
• Miscellaneous
  
  
  
  • Current consumption of meter is 1.3mA to 1.7mA (6mA with backlight)
    
  • Meter works down to 2.2V where meter turns off, battery symbol show at 2.4V.
    
  • Backlight only works down to about 2.7V
    
  • Reading is stable with varing battery voltage.
    
  • The meter usual need a couple of display update to reach the final value.
    
  • Viewing angle is good
    
  • Display updates around 3 times/sec
    
  • Backlight will automatic turn off in about 15 seconds.
    
  • Will automatic turn power off in about 15 minutes.
    
  • Standard probes fits fine, but cannot be seated fully.
    
  • Generally precision is within a few counts, but there are ranges where it is 20 counts out.
    
  • Weight is 354g without accessories, but with batteries and sleve.
    
  • Size is 175 × 81 × 47mm with sleve.
