5.0 out of 5 stars Just what I needed
Reviewed in the United States on October 13, 2011

I needed to determine which of my black wires was line vs load and this made it fast and easy. It also kept me from a good jolt when I thought I had all the electricity turned off but forgot one of the three switches in this box was a three-way and apparently on two different breakers. With a gazillion wires in this box it was still easy to figure out which of my lines was load vs line. Very straightforward and exactly what I needed. It'll get a lot of use.

4.0 out of 5 stars Best greenlee tick tester so far
Reviewed in the United States on April 23, 2011
Verified Purchase
This is my second GT-12 so far. I used to use the GT-11s and always hated the twist top to turn the tester on, which would eventually fall off. The addition of the push button makes this a much nicer tester. the only complaint i have about these is that the battery cover feels flimsy, you can push on it and feel it slide sideways. My previous GT-12 never lost the cover but it feels like a potential issue for those of us who use these often. The self check is nice however please remember too always test on a known live circuit first to make sure it works.

This non-contact voltage indicator seems to work very well. I have had no problems with the operation. However I do have a issue with the battery compartment door. It seems loose and even flimsy. But so far, 60 days, has not failed on me.

4.0 out of 5 stars Excellent product!
Reviewed in Canada on November 14, 2013
Verified Purchase
does just what it says, is easy for everyday carry. Greenlee has been highly recommended by professionals to me and I have owned an electrical testing kit from Greenlee for a number of years with no problems. Definitely recommend this product for it's capabilities and convenient size (Every day carry). The only thing I would recommend is that the battery cover be a little more durable, it's kind of delicate and the clip on it looks like it may break after a while. I will be careful with it but that is the only thing I could see that needs improving! Other than that, four stars... could always use improvement!!
