The controller does not work and Wayfair is refusing to refund me. They issued 5% refund and said I have to wait 5 months for a replacement part. Meanwhile it is almost $600 desk that does not work as sold/advertised. We are still eligible to return the item and I can’t get them to refund me for defective item. Additionally the desk is too low for me so I have to sit u comfortably u til this is resolved. I WFH and study - spend over 60 hours a week at the desk.
