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

Really good tester, does a good job and I love the GFCI tester button. The price is great, there is a more expensive model than this one but this one is just perfect.

Its a great product i loved it

it works great. buy an extra one for back up.

Works

Does exactly what it says ! Very useful for older wiring on homes where identifying polarization is challenging. Great to use before a home inspection and will save you time and even money before a home sale !

Excellent product, 10/10

its so easy to check the outlets in the apartment we live in. My landlord didnt like it at all. i had found 3 plug-ins that were not grounded. i was having a few problems because of i thought just one plug not grounded. anyways its easy to use, and very accurate. My landlord had to fix the plug-ins and some how ground them. this is a great tool.. tks... Another great buy from Amazon. and very speedy delivery, next day... KOOL

Delivered fast, works great!

nice

Very disappointed it looks like one of the prongs is too big and it doesnt even fit in any of the receptacles.
