Query: Does what is suppose to do.

I can't review much. But I used this tool for a few hours for multiple cable drops. This tester help me tester all cable and a cable that didnt work. The tester found the problem. It supports both RJ45/RJ11 terminals for regular phone lines if you installing any. I upgraded to more expensive equipment as work provided us with new gear.
