This was a great solution for our bathroom renovation. We replaced the vanity with a larger size, but moving the light box location would have been a debacle due to some existing conditions in the wall. This allowed us to have a beautiful sleek look without needing to move electrical boxes or purchase additional vanity lights. The mirror quality is perfect and the item came securely and safely packaged. 
It is VERY heavy, my husband installed it on his own but mentioned it would definitely be better with two people.
