I ordered 2 of these shades, 58" and 72" wide.  When fully closed, the floating rail had a bow in the center, due it it being all vinyl with no stiffening support.  In the description it indicates a stainless steel headrail, that is not the case.  All I could see was vinyl in any parts except the mounting brackets.  The shade operated fine, though, and in a smaller width the bowing is less likely to be occur.  For the price, on a smaller window, I would likely have kept it and been happy, but in my case I returned.
