Very happy

I love the size of it and that it tests the GFCIs

Great testing tool. Not sure if i can use the GFCI test button on regular switches. I have those old fuse boxes and not all sockets are GFCI (only in the kitchen usually). It would be nice to cover the button from accidental press if it will blow the fuse. I didnt try it on my regular socket but it worked on GFCI.

Its one of those tools that you need rarely but if you do, its really handy to have around. Sure, you can make due without it but it sure helps when trying to figure out which outlet goes to which circuit without having to get out the multimeter. It also beats carrying around a lamp or something else to verify the outlet is dead.

simple unit but does what it says it will.....

Nothing wrong with it. It works like it suppose to.
