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

Works like a charm. I had one of these years ago and lost it. Glad to have one back in my electrical tool bag. Great buy and a great brand tool. If you dont have one get one. Itll save you that headache when you have wiring issues

Works fine

Great tool to find bad plugs

Worked great, easy to use, cheaper than big box home improvement stores.

It does what its supposed to do!

Klein has always produced quality tools for the electrical trade!

When it comes to electrical products I always find myself drawn to Klein. This product has performed perfectly. The lights are bright and easy to see as well as the label. This is a great product that all home owners should have.

Great product, great price

Excellent tester, very straightforward to use. The lights are easy to see and interpret as the guide is printed right on the device. I used this to verify the polarity of a wiring project and tested a set of GFCI outlets in the bathroom (using the black button). All works as expected.

Great tester, easy to use, accurate, and durable.
