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

Gardner Bender products are very good and are very competitive with higher priced other brands. I have used this outlet tester multiple times and used it walking through a house my friend was looking to buy and found there was not a common ground connected to all the 3 prong outlets in the house. This was after it had been inspected! If you do your own wiring or just want to make sure current wiring is correct to an outlet, you can't beat this inexpensive, quality solution.

Great product, great price.

The media could not be loaded. Works as advertised. Came right away. I lost my cheapy 3 light plug tester in our last move and the house we purchased has several jacked up plugs I need to replace. I like that it has the GFCI tester is built in and it's seems to be good quality. It's fairly easy to read and understand. I liked my old ones red yellow green light configuration, but this is the most inexpensive one on the marketplace and whatever, just yellow and red. Made a little video of a GFCI outlet. It does have a bit of an ozone smell after plugging it in and testing the GFCI function, hopefully this isn't a safety issue.

Works great except it’s almost impossible to read the color code key - the white and yellow are nearly indistinguishable.

Lo compré porque se me arruinó un cargador de automóvil en un Airbnb, el contacto tenía un corto, pero ahora puedo realizar la prueba y estar seguro de la buena instalación eléctrica.

Good quality

It works, cheaper than stores, and came the next day.

It’s a good tool it’s a little small for the hand ,
