We really like this round mirror for our half bath. It has a hanging unit permanently attached on the back and a molly/screw to put into your drywall. It also has two sticky pads making a triangle out of the hanging system. You do have to use the sticky pads attached to your wall, otherwise when you clean the mirror or bump it, it really moves around. This only reason I gave it 4 stars instead of 5 is that there was a small scrape or imperfection in the glass, but now that it's been up for a while I can't remember where it is and it really wasn't worth sending back for a new one. Also, it was shipped to us FedEx, and for $2.95 that's a real bargin.
