The mirror arrived undamaged, but it had a manufacturing flaw that required an hour of my time to fix.  One of the support hangars on the back was not positioned properly when it was glued down, so I had to cut it free from the foam adhesive, clean the affected area, and apply epoxy to properly seat the clip.  Then I noticed that the glass itself was curved when I installed it, so it doesn't sit flat against the wall and the reflection is distorted near the sides of the mirror.  In the process of hanging it, the black backing left scuff marks on the wall that won't come off with a magic eraser.  On top of all that, it was on the pricey side for what it is.  Incidentally, a Delta mirror of similar size sells at a local store for less than half the price and it looks better.  I would return the mirror, but I'm not sure I want to deal with the hassle.
