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.

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.

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)

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.

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!

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.

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.

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.

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.

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

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.

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.

Great idea

For Is it me or is it USB?

I think this is a great little device. I have tons of usb cables that I need to check. I would love to see a version that can check lightning cables!
