Review on Noyafa NF300 Cable Tester Tracker by Tone Hatton

Bought Noyafa NF300 to test BNC cables. The device worked fine for 2 months, but now the reading is open for each cable tested. All cables were retested by feeding a signal from a video source into the monitor. The monitor received a signal on all cables which the NF300 tested as bad. You can no longer trust this device for accuracy. There is no warranty information on the Revain website or on the Noyafa website. All contacts on Noyafa website are located in China. I would not recommend purchasing this product if you expect it to last many years (or even months) in your kit.
