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

This product is really useful but the driver who shipped the parcel was not good and he obligated me to come to entrance.

Very easy to use and read.

Buen producto para labores eléctricas

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

Bought for several family members who are building new homes. They found several wiring problems right away. Good idea for everyone. Very simple to use

Great products came fast. very happy with the purchase

...this is a great circuit tester.

Klein products are the best! This is another great product. I was not paid to say this.

I was getting shocked by the fixture chain when it touched the top of my bald head. Yes, the white wire was on the black wire side, all is well now I hope.
