I am sooooo disappointed in this company.  My first complaint is that there is no description of the mounting hardware - what it looks like or how it fits into the window frame - prior to purchase.  I chose my size from all the listed sizes on the site but when received the blind - the mounting hardware did not fit the inside of the window frame (too narrow for the hardware). Blind was never taken from its packaging and I tried to return this but Wayfair tells me this was "made to order" and cannot be returned.  Blind size is literally chosen from dozens of available sizes - not "CUSTOM" - but not returnable.  BE WARNED! Make sure you love this blind and get some kind of idea of the mounting hardware - or better yet, choose a company that allows you to return the unused item.  Will not buy from this company again.
