I ordered 3.  Definitely heavy buggers!  The mounting devices that come along give you some wiggle room to make adjustments after you hang them if you have little nimble fingers.  The hanging process made my husband super crabby.  Be sure you know how to use the mounting things before you start as there are no directions.  (The nails go in from the top at an angle.). We used dry was screws with them if they weren’t in studs.  (Paranoid because of weight.)
Man!! They are gorgeous.  Definitely not the color pictured, but that is why I ordered them. I wanted them to match my antique bronze fixtures. They do perfectly!  Love the antiquing on the mirror itself. Recommend for sure.
