Review on 🔌 GE 50542 Receptacle Tester, Gray/Yellow - 3-Wire Light Improper Wiring Indicator by Tim Blandin

I have had two of these devices for almost 19 years and they both work very well for me. I'm not an electrician so to be honest I don't use them all the time but I do use them. What I like about this device is that it does not require separate batteries but uses power from the circuit. tested - IF power is on for that circuit. It's safe too! Hell, reading the results is as easy as plugging in when the circuit is assembled right side up. Great little reliable tool.
