Good quality and good value for money
Good quality, good value for money, easy to use and very useful.

A useful passive USB lead tester, but no cable current capacity display.
Useful to identify if cable has USB 2 and/or 3 data, or dodgy connections.I found one cable with no shield connection, and iffy other connections, a USB-A to USB-C cable with only USB 2 D+/- connections, and various cables with no data connections. I assume the ID LED is for micro USB OTG adapters.It would have been nice, for this to also included an estimated display of the total cable resistance of both power connections or the maximum power they can carry at 5V and higher PD voltages, for in-specification voltage drop; this requires measurements at both ends of a USB cable. This maybe cheaply estimated using a tiny microcontroller with multiple ADCs, to measure total cable voltage drop for the supply current to and from both the VBUS and GND LEDs (loads), to allow calculation and display on a tiny LCD or OLED display. I don’t know if the active USB tester, of this brand, provides such power capacity estimation with its active data testing, and is limited to USB-A/C to USB-C testing.

Every person should have one.
Every person should have one.This has to be one of them gadgets many just do not want to be without, You are most certainly at a great disadvantage not having one.There are a number of positives about this unit in what it will do for you, the main one is a “What If”You lost your lead to your phone, needing desperately to download or upload something to or from your phone.There is a spare cable that will fit your phone.However, Is it a Charge lead only, or Data and charge lead?As you may already know if it is a “Charge Only” lead you wont be uploading or downloading data because it won’t register on your device as a Drive.So now test all them cables to figure if its a data cable or a charging only cable.You probably have tons of charge only leads, Time for a sort out.The beauty about this unit is it tests for shielding.This on its own was a reason i purchased the unit.I could not find the original cable anywhere for a Peterson Guitar Tuner Unit, so was using this cable i had lying around, anytime this unit was connected it always had a noise, irritating but could never source where the noise was coming from but it was definitely this cable, why?Turned out the cable i was using was not shielded!Immediately I found and tested another cable the sheilding light lit up.I then tried that cable the noise was gone.I am sure many will find this unit useful, but for this purpose also as there are many USB leads out there of the various size that this unit is there to test and many have no shielding.Working in a recording enviroment ” Unwanted-Noise” is something you definitely do not need, even low frequency noise.Well designed a lot of thought has gone into this tester, It looks an awesome bit of kit and does the job as intended.Just take care connecting leads to it as not sure how strong the soldered points are to the board, especially if you have a box of leads to test.When inserting or removing keep the socket on the board your plugging or unplugging to between thumb and finger, just to give more support.Overtime these soldered joins might loosen, so USE WITH CARE.It isn’t the invention of the “Wheel” but its certainly very close, should be certified with an award for Ingenuity, Design, A product you are at a great disadvantage not having.

Cheap, cheerful and very good for testing cables…..
HiPlease see my photos that accompany this review, they can be informative.The second one in particular shows what appears to be a light brown piece of card. Well that turns out to be the clear acrylic cover with a peelable brown protector that you need to remove..!For the cost the testing unit seems to be very well made and comes with the stand and cover, see photos.In my opinion it is worth paying a little more for those.The board itself has enough printed information on it to be useful.The detailed two sided manual is very well written, one side information about the board and how to power it up etc. The other side about the pin outs for each of the connections, well the LED lights.I have included a photo showing a USB 3 based cable connected and the corresponding lights that the board displays.I am still learning as to the boards full capability, but that can be understood in time.My only very slight concern is the need to be a little cautious when plugging and unplugging your leads. Perhaps a touch of hot melt glue to hold them in place might be useful, so far they seem fine.Overall a very useful board and a very good price.I very much recommend this USB cable tester.I do hope that this review has been useful for you.

I had a huge tangled pile of cables filling up a drawer and now I have cut it down to six! I am not an electronics expert but, with the very good little manual, you soon get the idea and can sort out cables which are not working and which are, say fast USB-C or USB-A 3.0 and which are the older and slower 2.0.It allows for a wide range of (male-to-male) combinations: from (at one end) USB-A 3.0, USB-A 2.0 and USB-C to (at the other end): USB B 3.0, USB-C (2.0 and 3.0), MicroB 3.0, MiniB 2.0, Lightning, MicroB 2.0. I don’t think you can test USB-A to USB-A. The LEDs show the state of all the different pins and the manual helps you work out what they all mean. I felt like quite an expert after about 10 minutes of mucking about…The tester comes with a coin battery (you can in also plug in a power adaptor, which you’ll have to source. I’m not sure it’s worth it, unless you’re going to test many hundreds of cables). This means you test the cables themselves: you can’t plug them into devices and test them in action. This also means you are testing the type/speed of data connections and whether there is a power link. It won’t tell you directly what the voltage/power capacity of the cable is – you have to infer that from the cable type (eg USB-C is 60W+ at 20V) or get a power meter.I recommend spending the extra €2 for the acrylic top, which is easy to fit.It looks a bit Heath Robinson but is actually a great piece of kit at a low price and much easier to use than I feared.

Très pratique, voire indispensable pour faire le tri dans ses câbles : tester leur état et connaître leurs caractéristiques (charge uniquement, données, transferts haut débit…).Franchement top !
