Review on Network TesterTelephone Tracker Detector Finder by Jonathan Abreu

Works well. The sound in this machine is very strong when tracing wires. Make sure you don't use it for the sound on the poe switch as it will damage the test part of the device. This is my second. The toner still works so I use the damaged one for sound and the new one for sound with the cables unplugged and for testing after unplugging.
