This mirror looks pretty nice and it is worth the money, the center section of the mirror is 20" diameter and comes with two hanging brackets.
Cons: Although the frame seems to be made out of MDF and no metal, it is just painted in gray/silver and I realized about this after I actually bought it, I would have preferred to get the item model # CKH-MR-3317- Somette Modern Round Clear Mirror, at the end, I'm pretty satisfied with what I got.
