Works good!

Does the job. Does it in a *really annoying fashion* because every time you plug in a new cable it goes through the wires one at a time STARTING FROM #2, so you get a brief heart attack thinking #1 is borked before it gets to the end, pauses, and starts over and you see #1 light up as good.

Still, it's light, does the job, and is absolutely dirt cheap. Definitely recommend for the money, even if it's not perfect.

I used it to identify some 'mystery' network connections in my house. This tool worked great and was easy to use. I would have paid 4 times the price.

Strictly a continuity tester but cheap and it worked perfectly. I was able to see the open wire in the cable I was planning to replace.

Sw and battery cover are suspect(may not last). but for the $, great deal 'cuz it works

It saved me time and headache wondering if my connection was terminated correctly and I am a beginner!! Love this product!

it does what it is supposed to do and is inexpensive.

My new home came with a central media center where all Ethernet and coax cables were terminated. I had five of each. They were not labeled as to which cable was connected to which room. Using this device, I was easily able to determine that and to confirm that all eight conductors were wired correctly. One room was completely disconnected and the builder fixed it. I used an RJ45 to coax adapter (which unfortunately Monoprice does not sell) to test the coax connections.

Super...indicates on both ends

Great tester especially for the price! Small and lightweight. Beats having to run an external Cat5 to complete the loop for testing.
