I mounted two on top of each other based on someone else's post, thereby saving a lot of money off of Pottery B.'s version of this!  It was hard to hang these for just one person but I finally googled and found out how to create a template to lay out the screw holes.  I had to use drywall anchors. 

The quality of the mirrors isn't that important to me as the point was to provide extra light and accent, but the quality is actually fine. It's just each pane is so small one doesn't see much of oneself reflected in it, if that makes any sense! 

I would recommend!
