When we moved into our new home, I wanted something different for our sliding glass doors than the standard blinds. We have cats and the cheap blinds end up bent or they pull out from the top. I found these on Wayfair and showed them to my husband. They were inexpensive and he didn't think they would work well but told me to order them anyways if I liked them. Well..a year later they are still hanging up. They block out the sun VERY well. We get a lot of compliments from people because they've never seen something like this. The only reason I gave it 4 stars is because you do have to be a little careful when you are sliding them. The 4 panels like to be open a specific way.
