Lovely mirror, came well packaged.  My husband questioned the simple hanger that was attached to the back (the piece weighs 30 lbs) and there were no hanging instructions included.  He hung the mirror but the mirror hanger on the back broke 5 days later and it crashed to the floor, demolishing a double electrical wall receptacle, damaging the wall and frame of the mirror.  Luckily, no one was sitting under the mirror as they certainly would've been injured.  We had to have an electrician repair the receptacle.  My husband made new hanger for the back, along with a wall hanger capable of holding 100 lbs. and it is now hanging securely.
