This is a great mirror. It looks nice, and it seems to work well so far. It is pretty heavy, but that's not surprising since it's a large mirror. Unfortunately, I can also confirm that this is indeed tempered glass, because I shattered one when it slipped off of the corner protector and fell half an inch to the tile floor. Be careful when moving it and unpacking it, because it doesn't take much of a fall with something this big and heavy for a hit on the corner to break the whole thing. No one was hurt when it fell, though, because since it's tempered glass it just broke into little pieces in the box. I like the mirror enough that I just bought another one right away. I recommend it.
