False advertising.  Product description claims the mirror is 18" wide but the actual product is only 16-1/8".  Called Wayfair to explore options and returning for a refund was the only option we could agree on.

Note to Wayfair:  Use the specs from your supplier and don't trick customers by rebranding someone else's stuff:  Dowell Item # 5004 1831 15M
