Simple but works great. I had 1 box that was recessed about 3/4" deep and on top of that the installer cut a hole about 1/2" too big on the top. The wall panel covered it but the top rosette was awful because it moved every time I tried to use it. I never noticed him before because he was in the guest room. I installed it and was able to take a piece of drywall and fill in a bigger gap than needed. The new drywall standoff overlapped where the screw goes, but I just drilled through it before installing the screw and it worked perfectly. Now the socket feels solid like it should. A simple product that does its job. Thank you!
