Review on Klein Tools NCVT-2 Voltage Tester: Reliable Non-Contact Dual Range Tester with 3 m Drop Protection by Tyler Owens

I can plug it into an outlet and it works 2 times out of 3. Then I can put it in my pocket and walk away and it works as soon as I put it in my pocket. In my opinion, this is something you don't want to trust your safety to. I've had too much time to return or replace it so I'm sticking with it, but I'd be wary of buying it. Don't know if it's just what I got or not, other reviews seem to like it. That's why I bought it, there were primarily reviews and the name Klein. Unfortunately I will look for another.
