I am editing my review.... I wish I could give these a ZERO.  Worst purchase ever made on Wayfair.  They broke 4 months after having them.  I think they are meant for just looking at and not moving.  Everyday I opened them and closed them they stuck more and got noisier.  They broke one panel at a time!  Only 1 panel still hanging now. I bought these to separate our doorless bathroom from our bedroom.  It is a very wide opening from the bedroom to bathroom.  They are nice, made up of a thick material that blocks out light but they squeak horribly when you open and close them.  The point was to allow my husband to get ready in our bathroom on his early mornings while I slept but the squeak wakes me up every time.
Also they move with very little air flow.  When we have our ceiling fan on it moves the blinds and the metal pieces hit each other making noise all night.
