This shade sail is really great! The material is very durable and well enforced. The hooks at each corner also seem really strong and are easy to work with when hanging it up. The only complaint I have about this product is that there were absolutely no instructions whatsoever to help guide you or give you any clues on how to hang it up. Thank goodness for YouTube videos. Even with that said I am still giving it all 5 stars because I am totally in love with this and will be buying more in the future!
