Works. No issues when testing with a cable I put together. Also worked with a cable I made intentionally bad to find the fault. Works fine for a cheaper, simpler cable tester. No issues or complaints.

This device is pretty good. For $20 it's hard to beat. Any others that I looked at are around $60 or more and I just needed it for one tiny job. I wouldn't recommend this for somebody who does this on a regular basis, but for somebody who is just doing a simple job at their house, this is definitely a go-to.The one downfall to this device is the range isn't very large, now. This could be for many reasons, including the houses old, so there's more cable than needed.Honestly overall though this is a great device, feels a little bit cheap but it works and does the job!
