I searched a long time for a suitable insect repellent for our outward opening balcony door, this lateral Rollo was the perfect solution. Compared to other similar shade solutions, it was cheap. I imagined therefore the question: Is he any good what? I ordered him. The delivery was fast. The first impression was positive. The instructions should be studied very carefully before cutting and installation. The shade is very robust and stable. One can only terminals him, we did screw it firmly to the door frame. Really great part, highly recommended!
