First of all, this thing is BIG. 8" x 8" So, if it''s going over a door with a header, you may have trouble fitting it.
2nd-It has a HORRIBLE retrofit design. If you are replacing an existing doorbell, and plan to "just cut a hole, drop it in and tighten screws", like surround sound speakers.... NO, this will NOT do that. It has a few small (VERY small) tabs that pinch the drywall on its sides and top/bottom. A backbox with dog-ears REALLY needs to be standard.
3rd-The screws. The WHITE screws, which should be used to hold the cover on and disappear, would not go into the backbox, to hold the cover on. They were too big for the pre-tapped holes. The smaller silver screws fit perfectly.
