We have around the balcony to protect the sail for months in summer use from the sun, the apartment heated less because the radiation is very well received by the sail, it's right on / under sail very warm air and under cool shade. Since we were not enough fasten tight the four mounting holes, we have double seam along the folded, made additional holes (with knitting needle or canned milk aufstecher because is so moved, the fabric and not severed best) and keyrings drafted, it widerum carabiner and now one nice flexible. There was so much wind on a cheap key ring is bent. Nevertheless, his home-made hole in the seat he laid no torn bit. Fantastic quality if rather the attachment is broken as the sail even a bigger hole. There is also a very pleasant light. By UV density and dark green, already some light is lost, but in direct sun produces a very angehmer gedäpfter optical sound.
