Network Cable Tester RJ45 LAN Cable Test Support POE for RJ45 Cat5 Cat5e Cat6 Cat6a Cat7 UTP/Shielded Cable and RJ11 RJ12 ethernet Cable Tester （Battery not Included）

Great product that works and does the job it was designed for. It can be used to test cables built by user and for continuity of long cables between rooms. I plugged a cable that I knew was working into the ethernet wall jack in bedroom connected tester to cable then connected other unit of tester to cable that plugs into router on other side of house. It showed a fault. I checked cable in attic and found where rodent had eaten into cable.Well worth the money and seems well made even though its plastic. I would buy it again.

Once I had a battery loaded, I could figure out which cable terminated in which room in a CAT6-wired home within a few minutes. Good price for something I will use very rarely, yet saved me a lot of time of trial and error.

It's good for detecting continuity of your Cat5 cable. It saves plenty of time when diagnosing random issues.

Needed it to figure out which of the Ethernet points in my new place connected to which rooms/outlets. Got the job done quickly and easily.

Works as one would hope. Good product at a good price.

Got this to test some connections I was making / ethernet cables I was terminating. Really handy little device and super basic operation. Helped confirm all of my crimps were solid before installing things in annoying locations.

The product did not work after one month, tested it when It first arrived, worked fine, needed it one month latter and it did not work, confirm it did not work on a brand new factory cable.

Good tester, good quality
