I bought this sail for my patio so I could have some shade, it was not easy to install even when I watched lots of different how to videos. I had to keep repositioning it until I finally got to the point where it did not have as many “written“ the middle ( it was almost like of it had an irregular shape even when it is supposed to be a rectangle). After all the hardwork done and just only less than 1 months in place I just woke up and one of the corners just broke completely so it was laying on the floor from that corner. At the beginning I thought that it had “unhealthy“ the pole but it actually broke from the loop. I went to my order history to see if I could return it or exchange it and apparently I am out of my window frame … wasted time and money. I will try to contact wayfair directly to see if they can either give me a refund or send a replacement.
