This is a really nice Sail Shade. The material is very sturdy and it's water-resistant. It looks great to cover a backyard patio. I wish it came with poles. I had to go buy some wooden poles to put in the ground and then cement them. Not an easy job. Also, I could not attach it to my house because it would have torn away from my gutters. I live in Florida and we have hurricane winds here. I ordered the square one and it only came with 2 hooks. I had to go buy 2 more. Once it was up, it looked great and did the job. More hardware and poles would have been nice as well as an extra, just in case.
