I was in need of a Network & Cable Tester for an important project when I stumbled upon this product .As a result of my tests, I determined that its a reliable and efficient tool, perfect for Industrial and Scientific use. i especially liked its easy-to-use interface and accurate readings. However the only downside is it could be a bit more affordable. Overall, I'm very happy with my purchase and would highly recommend it to anyone in the market for a Network & Cable Tester..
