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

Does exactly what it should do.

Easily checks for proper voltage, proper wiring. Bonus is testing GFCI outlets for proper safety.

I wire houses residentially and use it everyday. Its the kind of quality I would expect from Klein Tools.

Works as intended, but buy two at minimum. They do eventually go out and you’ll need another to confirm that the plugs in question is indeed putting out the electricity it says

Works as described!!!

Gran probador y fácil de utilizar

Solder connections inside device cracked and came apart. Doesn’t work anymore.

Great compact tool to have, to test your outlets. The printed guide on the tester is easy to understand.

Keine Beschreibung von Volt in der !!!

A must have for people who do quick electrical jobs, fits in the pal of your hand, reads immediately!!
