The first fan we received was warped and wobbled at high speed once installed.  We requested a return and was shipped a replacement 4 weeks later because Wayfair was out of stock on this item.  We had to pay our installer another $75 to install the replacement which works fine.  It looks great and is very quiet.  We are happy with the fan but disappointed that we had to pay for installation twice due to the defect with the original fan.
