After several attempts of purchasing a frameless round mirror from another website and receiving defective mirrors (visible imperfections in the edges of the mirror), I attempted to purchase this one from Wayfair to once again receive a defective not perfectly round mirror.  I wound up getting a $15 round mirror from Ikea and it's perfectly round.  I either have a bad string of luck with these mirrors, or the manufacturer does not have a great quality control check.

Cons: imperfections resulted in the mirror not being perfectly round
