The plastic arms that secure the plate to the wall are too thin. I installed 3 boxes, and all of them wound up with at least one broken arm. One box I had to secure to the wall by attaching braces behind the wall and using long screws to drill though the plate into the braces. On another I used a normal outlet box frame I already had (with strong arms), then ground down the protruding portions of the Easy Mount (with broken arms) on the rear and screwed it into the box frame. What should have been a fast job took me hours just because of the flimsy plastic arms these plates were built with.
