Bought the 55.5 by 43.5 mirror.  The mirror can be hung either way and comes setup with mounting hangers for such.  Came very well packed.  As others have mentioned, in one of the corners the black and MDF frame was separating from the mirror a little.  Used a little clear silicone and some weight to hold in place while drying and all good.  I guess I'm glad it did this right away versus down the road as was easy to fix prior to installation.  Related to the MDF gray faux wood.  It does have some texture so gives to a real look.  It is a consistent color throughout, as well as finish.  If buying more than one for a room, the quantity ordered should have the same look and feel.  Overall, would I like to have real wood, yes, but with real would also have issues with corners cracking, moisture in a bathroom setting, etc.  This is a quality trade off.
