Let me start by saying that this mirror is excellent. My fiancee loves it and says that she can really tell the difference between it and less expensive mirrors on the market.

The flaw is that the bezel that mounts to the wall is slightly too small for a standard round retrofit box. The mirror mounts and fits as is intended, but you can see just the smallest blue lip around the edge of the mount if you are looking from the side. You can avoid this by repainting that part of the wall, so the box matches the wall color; however, it would have been nice if the mount was just a quarter of an inch larger in diameter to hide this. It really is unfortunate that the engineer that designed this didn't take that into account.
