I've upgraded some of the switches and outlets in my house. In the master bathroom, they decided to cut a hole in the mirror and put sockets and switches in the hole.

I found Effortless Electrical Spacers and decided to take a chance. Well they did their job. The switch and plug fit perfectly, do not move and are flush…
