Review on Power Gear Tester 110V 125V 50957 by Bryan Hill

Just works. The instructions are clear. I can't fault that, especially the price. Some people complain about difficulties reading the panel on the device. For me it was no problem. Also, if you did your job correctly, you would only light the two rightmost bulbs each time (good wiring and grounding). Of course, this isn't just a GFCI tester. It will check any three-prong outlet and give you an idea of how it's connected (e.g. if the ground circuit is open or the neutral is swapped to ground, etc.). This is very valuable even if you don't have a GFCI. And if you have a GFCI, you can check if it really works by clicking the button. It's an added value but not a main course. Nothing bad so far, let's see how durable it is.
