Klein Tools 80077 Voltage Tester Kit with Electronic AC/DC Voltage Tester, GFCI Outlet Tester and Non-Contact Voltage Tester Pen, 3-Piece, Green

Good tool for an electrician

Dies exactly what you need it to. But if you have an older home buy the whole kit one. My panel wasnt labeled and the kit helps show what receptacles go to what circuit in the panel. Both are fabulous

Okay for the price

je suis très satisfaite de ma commandeé

We used this to test diy gfci installs and also, to carry in the rv to make sure that campground outlets do not fry the rv electronics.

good tool

Great Product ..... Exactly as described...... A+

Does what it’s supposed to and way better quality in build and brightness than the Harbor Freight Ames brand.

Quality Klein tool, nothing else to say.

Works.
