Delivery guys were awesome!  I ordered 2 sets.  The smaller set had weak paint and I will have to repaint.  The larger set (72 inches) does not slide smoothly and squeals.  Not worth taking down and dealing with a return, but definitely takes away from the value.  These are manufacturer issues and not so much Wayfair - but I'm wondering if Wayfair's prices are lower because the quality of what they sell is also?
