The blind does the job. The installation was the first (I have ordered a total of 4) Rollo complicated, the description is rather confusing. But if you have it only once out how it works, it comes within 2min. I also ordered 2 for my balcony door. Unfortunately, it turned out that the full length can not be used because the substance is simply glued only at the bar and comes off (!). So lost a few centimeters, because you can not fully roll. Otherwise, I am satisfied!
