My only problem with these shades is that the website was incorrect in calling them "Room Darkening" -- they are "Light Filtering". Instead of returning them, I decided to add a pair of "Blackout" drapes on top of them. That did the trick! The blinds work fine and filter bright daylight while giving me privacy. I purchased similar blinds for other windows in my home for 3 X the price! So I am very happy with them now.
