Product reviews for RJ45 Loopback Tester

Received quickly and was packaged well.  Did one test on a modem ethernet port that was no longer sending a signal via cable.  Tester did not light up, so I assume it worked as it should.

So glad I ordered this. Came in handy since it's bulky in size. Have made them myself but can easily lose them among the other tools I carry in my bag. Besides, when the customer is watch you troubleshooting, they are impressed with the looks.
