I ordered 4 of these blinds in the first order. 2 of them were broken. 1 didn’t stay down and 1 wouldn’t roll up. Wayfair customer service was terrible. The first time I called, the person must have been getting off-shift and disconnected me after 12 hr at exactly 7pm and said there could be no exchanges. The second customer service said I could exchange and supposedly took care of everything. After a week, I learned they only submitted for 1 blind to be exchanged. Contacted them a 3rd time (at 9pm on a Sat.) and I think the person had been drinking based on their response (or lack there of). I ended up paying 16 to return it and ordered the replacement myself because I wanted to be done with this. 
I did give it 2 stars because though there was a high failure rate, when you do get one that works, these Roman shades are amazing. Quality fabric, and simply beautiful when up. I will not order from Wayfair again though.
