The shade itself is fine, but the installation was ridiculously difficult. It was so tight we had to fight to get it in. The lift cord stop allowed several inches of shade to hang down when the shade was as far up as it would go. There were no instructions on how to fix this, so we tried one thing after another. If we set it so that the shade is entirely rolled up, it wouldn't roll back down. We finally compromised, because we were so frustrated that it was no longer worth the effort.

I'm sorry you had a problem with your shades. It is very important that you order roller shades using the width of the actual opening at the top of the window (only). I'm glad you were able to make the width work.
The shade not being roller up properly is usually something that you can fix. I will contact you to see if that is possible. If not, we will remake the shade for you.
