I didn't even bother to hang them once I opened the box and got a whiff of that terrible odor!  The header was dented also, which I tried to tell myself was okay because it would be covered by the valance.  I let the blinds sit for a day hoping the smell would go away but it didn't.  Ultimately I decided that anything made in China that smelled that bad wasn't anything I wanted in my home.  Will return.  Too bad I think they would have worked well.  Wayfair, stop selling these.
