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 great

Good

Excellent feature. Tells you whats wrong before opening. Great for inspecting wirirng. Saves a lot of time. Very handy.

I dislike this product, after almost 1 month of use the gfci receptacle tester showed incorrect readings although the circuitry was correct

Easy to use and simple instructions. Does what it says on the website

It work perfectly fine for the price

Works perfectly. I recommend highly to anyone doing electrical work.

Purchased to complete some electrical work with GFCIs. Worked as expected.

Work perfect

I don’t even understand all the features of this gadget. I mostly wanted to stop running around to find my husband an electrical item to test plugs. It works for that and apparently much more! Wish I found it before he changed out all of our outdated outlets.
