If you dont know, dont guess.

Would Recommend

Did what I needed it to. Helped test wires to make sure all lines were dead in a panel when I didnt know if my breakers killed power due to bad labeling. Got my dimmer installed and the wife is happy.

non contact tester waaaay too sensitive

Would Not Recommend

non contact tester activates a foot away from outlet etc so it's useless to localize voltage source.

Tester failed out of the box.

Would Not Recommend

Did not work out of the box. I purchased this as a replacement for one that failed at 6 months of use. Obviously a quality control issue with this model.

Fantastic Klein Tools GFCI tester

Would Recommend

This is a fantastic GFCI tester unlike many others in the market as it gives the actual time it took for the GFCI breaker to trip when testing - very useful to check if the GFCI outlet is up to spec.

Sturdy, well built, electrical testing device.

Would Recommend

Bought a new one that I beat up over the years. The flashlight portion still works and I’ll keep using it. The new one works just as well for both functions. It is a well built product and I’m very satisfied with it. I’ll get another replacement if I kill this one.
