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

Perfect for a quick troubleshooting of a dead outlet or extension cord before you pull out the voltmeter. Easy to read and understand the light codes. A must have for any homeowner.

Easy to use!!

Worked great for a week and died

This is a simple device for a simple purpose, and it performs beautifully. I plan to mainly use this device to ensure that an outlet is dead after the breaker is turned off, but at this price the additional functionality is a bonus. I bought two, and they both work correctly. I didnt try to test everything, but I purposely mis-wired an outlet by swapping neutral and hot, and the problem was correctly identified. Id buy again.

Worked As Stated

Worked just as it should.

It works as advertised. Simple operation, just plug it in and it tells you if your outlet (or other wiring) is wired wrong, and how its wired wrong. Quick, simple, compact. What more could you ask for?

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

Very solid, good price, just be careful when pull it from plug, it take little force

Great item works perfectly
