Great tool

For Is it me or is it USB?

This really takes the guessing out of the appropriate cable to use. Very simple to use and a really robust bit of kit.

Beautiful!

For Skully

Skully is the flaming skull PCB badge that I never knew I needed, but I do! 🤩💀🔥
Shipped fast, packaged well, thanks!

The USB cable continuity tester (type A to type B cable)

For USB Cable Tester

The USB cable continuity tester (type A to type B cable) functioned as advertised when I used it to test some cables. Shipping was not a problem as it arrived in a bubble pack with no signs of damage to the package or the contents. There was an insert that was brief, but complete. The documentation gave the official product name and a picture of how to use it. What more is required? Communication was a few emails. Everything was as expected, so I first thought to give a three star (all ok) rating. Upon pondering the star ratings, I rejected their labels and went with a five star rating (as expected with no problems) as most advertising exceeds the actual product delivered. As the device is simple, I do not expect to have any problems. As the device uses a lithium coin cell as a power source, replacing it should not be needed for years as lithium cells have a very long shelf life (up to six years). I intend to check new and repurposed (unplugged and reused) cables (I change things around less than once a year). How often do you check your USB cables?

For Is it me or is it USB?

Tested the usb cable i bought this for and apparently its me.. Tester will come in very handy and I really love gadgets

James | Jan. 2, 2022

I love this thing

For Skully

The quality of the effect is amazing. Took me a little while to get around to reviewing it but I finally busted it out and gave it a test run and I love it.

A massively useful tester to have on hand

For Is it me or is it USB?

The tester arrived faster than I expected and works great!
It would have been nice if the included explanatory business card had included info on *exact* meanings of the V+ and GND lights. I ended up needing to do some Googling when I first encountered a cable that only lit V+.
Otherwise, no complaints. Super handy.

Terence | Nov. 4, 2021

Very useful device -no need for documentation

For Is it me or is it USB?

An easy way to separate power from data transfer USB B cables since they never come with markings. Doesn't accomodate USB C cables however but appropriate adapters are available.

Kevin | Sept. 14, 2021

Works Great - Type A Port Tad Fragile

For Is it me or is it USB?

Works great, so happy to have gone through the pile and eliminated all the annoying power only micro USB cables. My only complaint would be the type-a port can be a tad fragile, keep an eye on it with shorter cables that you dont pull on it too much. I shored it up with some hot glue and its all good.

Mark | June 7, 2021

Stunning!!

For Skully

This is a really lovely badge that looks even better in person than pictures can show. Extremely well made!! Love it so much.

William | April 27, 2021

Excellent product

For Is it me or is it USB?

Great little tool. Service was quick and I've already sorted all my cords. I always use a 'charge only' cord when at a public charging station.

Luis Fernando | April 7, 2021

I love it

For Skully

The badge is incredible. I already added to my backpack with my other badges. I really loved it. The lights are incredible and I loved that depending of the position and movement, the lights turn off or on. Great buy!!!!

Luis Fernando | April 7, 2021

Useful for test my cables

For Is it me or is it USB?

It works incredibly well, I don't know how this is not on sale everywhere. Very useful to test my USB cables. Maybe we need a USB C version in a future (My gf told me)

Mike | March 4, 2021

Awesome product, does exactly what it's designed to

For Is it me or is it USB?

So easy to use and it works exactly as expected. There are larger products you can buy from China that come with many ports of all types, but those require a power source. With this one, you can do all the testing wherever you have the cables and it works fine with adapters. You'll just need a Micro-USB-M to Mini-USB-F as well as a Micro-USB-M to USB-C-F to cover all of your needs. I am shocked just how many of my cables are "charge only". No wonder I have run into issues a number of times. This device is a must-have.

Cameron | Feb. 23, 2021

Super Useful Tool

For Is it me or is it USB?

It's ridiculous that cheap micro USB cables will often leave out the data wires to save a fraction of a cent. This little tool quickly identifies the offending cables, and has definitely saved me frustration.

Andrew | Feb. 9, 2021

USB Cable Judgement Day!!

For Is it me or is it USB?

If you've got enough USB cables around that there's no point in having the 'dumb' ones around...this baby will be the judge, jury, and you're the executioner. I went through all of mine and did just that. Now I know that if I grab a cable and hook it to a microcontroller or something, I won't be pulling my hair out wondering what the hells going on. Love it. Worth every penny. Shipped fast too.

Question though, with an adapter, will this work with non micro-USB cables or USB-C cables?

Response from nerfhammer | Feb. 9, 2021
I would expect that it would work for Type A and USB mini via adapter.

It may work partially for USB-C but not accounting for the redundant pins USB-C has (multiple pins connected to the same line; in theory only a subset of the pins for a given line could be broken) or the 6 additional data lines added in USB-C.

A. | Jan. 26, 2021

Works like a charm!

For Is it me or is it USB?

Ordered on the 20th, shipped the next day, arrived in Yurp on the 26th. Excellent service!

The device is simpel enough in operation: all lights, power + data; two lights (the right ones, natch), just power. Any other number and combination of lights, throw the cable out! Great!

Andrew | Jan. 12, 2021

Definitely a Must-Have Device

For Is it me or is it USB?

Great little circuit. I had been frustrated transferring files from my Win 7 box to my Kindle and it was all because I had the wrong type of cable, i.e., a charging only cable vs a data and charge cable. I bought two of these so I could give one away to a friend. A video is available for this device.

Scotty | Jan. 9, 2021

Awesome little tool!

For Is it me or is it USB?

This is really great for quickly taking the guesswork out of programming devices with potentially dodgy micro USB cables. Can't wait for a USB-C version!

Michael | Jan. 6, 2021

Nice, one trick pony that did not empty out my bank account.

For Is it me or is it USB?

I have some cables that are questionable. This helped me out nicely. I was able to get rid of some dead/broken cables.

Micah | Jan. 4, 2021

Fantastic product -- Every USB cable I own has been checked

For Is it me or is it USB?

There's a glut of shoddy USB cables on the market. Almost every device these days includes one in the package. This is the perfect tool to check (and as often necessary, apply the mark of shame) for cables that don't meet the spec.

Stephen | Jan. 2, 2021

Great gift for techy friends

For Is it me or is it USB?

I bought 4 of these for Christmas gifts. They were a real hit. I had two recipients tell me they were used the day after Christmas to test their cables. I know one of them was placed into a "Go bag" to be ready for use anytime. Regardless of price one of the best received gifts I've given in years. The device can find cables that are defective and determine if a cable is power and data on just a power charging cable.

Günther | Dec. 25, 2020

Great Product.

For Is it me or is it USB?

Thanks. Finally I had a chance to remove all my old cables that are only good for low power charging. Quick delivery to Europe.

Klaus | Dec. 25, 2020

Great Product

For Is it me or is it USB?

Great Product for checking Cable and find some that will good work with Garmin Edge Cycle Computer. Delivery to Germany was also good and quick.

Carrie | Dec. 7, 2020

Excellent artwork and LED animation

For Skully

This badge is really high quality, the artwork is fantastic and the flaming LED flashes that gradually die out are great. The added benefit of it responding to movement is the cherry on top. A great badge, super stoked to add it to my collection!

Tom | Nov. 2, 2020

Excellent. Exactly what I wanted.

For Is it me or is it USB?

It does one great thing. Weeding out impostor USB cables. Shipping, documentation (not necessary) and communication (why?) were beside the point. Would definitely buy again.

Alexander | Oct. 8, 2020

It should have been made a long time ago.

For Is it me or is it USB?

I have a bunch of USB cables from trade shows and determining which ones can be used for transfers is extremely useful. This came complete with a battery so I was able to use it right out of the box, er envelope and its very easy to see which cables are good.
Too bad we're moving to USB3 cables now, but as long as I have raspberry pis and similar devices (which should be a long time) I will get lots of use out of this doohickey!

Andrew | Sept. 14, 2020

Handy bit of kit.

For Is it me or is it USB?

Does exactly what it says on the tin. It would be great to have something this simple but capable of testing usb to type b, c, micro usb etc all in one package.

Chris | Sept. 7, 2020

I knew it was USB.

For Is it me or is it USB?

This seemingly "obvious" device is going to save way more man hours than the price of admission! This particular device will never leave my desk or desk drawer, because I'm reaching for it at the first sign of oddities from now on.

Aaron | Sept. 4, 2020

Exactly what I wanted.

For Is it me or is it USB?

Everything I wanted and nothing I didn't. Already used it to go through my stash of cables and found several that were either making intermittent contact, or were completely shot.

The only critique I have is that the pictures show a USB-A port that has through-hole soldered supports, and the unit I received has surface mount soldered supports. I'm concerned this might not be as sturdy as the through-hole model. If the pictures were updated to reflect that change I would've had no reason to be concerned, and would've been 100% satisfied instead of just 98% satisfied.

Great product. Would buy again.

Gordon | Aug. 23, 2020

Very Handy Little Tester

For Is it me or is it USB?

Nicely executed. I've used it several times to find a proper cable for various applications. Now need a similar one for USB-C.

Lawrence | July 25, 2020

I am so glad I bought this!

For Is it me or is it USB?

30% of my micro usb charging cables were “slow charging.” I got rid of them and am now assured that when I need a charge that it’s at the fastest rate possible because my time is valuable

Alan | March 18, 2020

Great product

For Is it me or is it USB?

Simple, easy to use, works as described.
A real pleasure to put aside cables that will not transfer data or fast charge.
This little board does it really nicely.
Would love to have usb c version.
Thanks

Marc | Jan. 7, 2020

Good product. Would recommend.

For Is it me or is it USB?

Works great. I would like to put it inside of some kind of shell or case while being used. I'm afraid that I'm going to break it when plugging and unplugging cords.

Katherine | Dec. 26, 2019

Sanity-preserver!

For Is it me or is it USB?

This is great for those times when you really cannot see why a microprocessor can’t be flashed - and it turns out to be the cable. Much easier than tagging every usb cable. Those “no data” cables are good when you want to be sure nothing is downloading data from your device while charging. This device is a useful piece of kit. Bought one for me and one for my son.
