DataShark Network Cable Tester - Cable Mapper, Check Continuity - Test Patch Cords or Installed Cable Runs

Works great! Helped me find the bad crimp and fix it without having to mess around with something that looks like I should be finding ghost with.Thank you!

The first tester sent did not work. A second tester was sent this one also wouldnt work. On both units the power light was on but it wouldnt light the pin out lights. I thought I was improbable to have two bad units sent. I went out and bought a new 9V battery, this fixed the problem. The first tester was more than likely not faulty. If you have a problem, toss the battery that comes with the tester and buy a new one.

A great product for the money if what you want is to be able to identify your home network wire feeds. It is simple to use and does what it says.
