I bought four of these adapters. They weren't compatible with the GFCI outlets in my garage and were breaking circuits, and this may be due to the adapter pressing the button during installation. I couldn't tell. He did it four times four. In all other outlets they have worked great and look great. Design wise, one of the issues was that I felt the ground pin wasn't installed properly as it was loose in the unit and I worried it would break during installation; They didn't, but I would be suspicious if I had to uninstall and reinstall them frequently. It's a decent product at a very good price but I'll probably get something better in terms of quality next time I need something like this and I'll confirm they work in GFCI sockets.
