I ordered two pairs. One pair was perfect but the other had some flaws. I used the very excellent system to complain and received a replacement pair within two days.  I didn't even have to go to the trouble of returning the flawed pair as I was told I could just dispose of them however I wished.
Sometimes, the quality of a service is only appreciated when something goes wrong, and my positive experience means I have no hesitation in recommending Wayfair.
