Review on 💡 Neoteck Non-Contact AC Voltage Tester Pen - AC 12-1000V, LED Flashlight & Buzzer Alarm for Live/Null Wire Detection by Terrell Ciula

The Neotech voltage tester did not disappoint. This solved my problem. The light switch in the hallway shorted when I turned it on. I had to replace it but there was no way to tell which breaker to turn on as it wasn't labeled on the panel and there was no outlet to see if the bulb would light up. I had to turn off the main line and turn off all electricity in the house. At Neotech, after removing the switch plate, I was able to verify that the switch had power. Found it on my second try and was able to replace the switch safely. It is easy to use and there is no doubt that the circuit is live.
