Gardner Bender GRT-3500 Outlet Receptacle Tester & Circuit Analyzer, Indicates 5 Wiring Errors, Easy Read Chart, Comfort Grip, 120 VAC , Black

I own a small construction company that focuses on reside and commercial renovation; I used this often as it is a great time saving device that is incredibly durable and accurate!

Works well to ensure my electrical is working correctly in my RV when I hook up to shore power - and prior to turning on any of my major appliances. My only criticism is that it is easy to hit the GFP button, which then trips breakers which I have to reset. But at least I know that feature works as well!

it works good, easy to use n easy to read

Fácil de usar , buena calidad y muy útil

lo estoy usando y si me funciona bien

It does exactly what its supposed to do, and allowed me to identify problem outlets in my new house.

Quick read on an electrical socket if ever in doubt. The LEDs (see product picture) tell the rest of the story. So easy to use!

I inspect apartments and houses for NJ state housing and this tells me if a unit will fail for wiriing issues

Perfect for the added comfort of knowing all is well

For a tool that is a safety tester, its not all that safe when its hard to read the color coding label on it. I used a black marker and filled in the white markers, which helps, but if you dont have good vision, its safer if you write it out on a big piece of paper. :D But everything else is fine, the GFCI test button responds well, and its very sturdy. And I like that its rounded rather than edged, so it fits nicer in your pocket.
