The first one I ordered arrived with some evidence of having been a return.  There was an obvious flaw around the edges of the mirror and the box itself had a number of layers of tape on it.  I opened a chat with Customer Service and they issued me a return label based on the photos I sent of the flaws and the box, plus I had a replacement mirror in less than 24 hours!  I am more than happy with the new mirror, and I highly commend Wayfair's customer service.  Well done, everyone!
