As the so's always with the umbrellas, they're never there, where the sun is. Since our buggy but no way is an awning to mount, I had no choice. The screen is not really suitable for a thick frame, he is not open wide enough so that it only just fits so. The adjustment is a thing in itself, since you have to play around quite often and find for themselves the best stand. But as I said, there was no alternative way, it served its purpose
