No continuity probe
Great product and covers most all the cable type needs, but DOES NOT have a continuity probe tester, typically where it also doubles as a banana plug tester.

Really easy to use, USB-C would be nice
Device stopped working after several weeks from purchase. Luckily the fix was easy - only had to resolder a single power wire (see the photo attached). Other than that it's working fine - feel sturdy and it's very easy to use. As others mentioned - it would be great if it also contains USB-C port.

Worth having if you have any cables
This has made life easier. Now I test the cable first before seeking system repair. With this 15 plug teater, there is no cable or connector I can not test.

Great device I will use all the time, sad it had no instructions
Sturdy and well-built product that I will use all the time. It was easy enough to figure out the basics, but I wish it could go further, maybe with some instructions. It's kind of a good or bad result. It either works or it doesn't, instead of indicating a short or wrong pin configuration. It's just a quick way to check if a wire is functioning but not how well it is doing it. Still, it's a great tool to save time when unsure if a cable is working. I like that it tests HDMI, audio, video, and networking cables.
