I have had this for maybe a month at most. Have used it five/six times and now it no longer works. Either can't power it on, turn it off if I get it on, or detects power when it's on. Sometimes it is just on with a green light that does not detect the presence of power in an outlet or lit light bulb. That seems rather hazardous and can lead to harm if you are a novice to electrical work. Buy something else, this was a massive waste of money. If I could return it, it'd be long gone.

This is a great voltage tester. Although it is small and lightweight, it has sturdy and well-built feel in the hand. Response time is instantaneous. Quality and precision of workmanship is superb. The tip has very sharp sensor, and a red LED when in range and green when not. It does not work only on 12V circuits and metal sheathed conduits. It would work on cat5 and thermostat cable connections. Excellent tool!

I have a multimeter, but this tester is much easier to use if looking for a live wire in your circuit. Makes my home project a lot quicker. My house has a 2 way, 3 way, and a 4 way switches that I wanted to replace with smart switches, and this tester made my job a lot easier.

This product was easy to use. The red/green light system makes this simple enough for ANY amateur home improver to use who probably has no business doing their own electrical. I was able to test the circuit, didn't get electricuted and didn't die. For not dying, I give this product five stars.
