There are a few things we really like about this shade sail. The color is very vibrant and the tarp -like material seems very study. The grommets are securely placed and seem sturdy. We ordered the large one and it will provide a lot of shade. Our only complaints: there are no instructions for hanging so we will have to get help from our local hardware store. The write up on wayfair should have indicated  that we would need to buy a separate kit for hanging. This lack of information is the reason for 4 stars instead of 5.
