We’ve only had this shade up for a couple weeks now, but it’s made a big difference on how cool both our patio and the backside of our house stays on hot days. The install was a bit frustrating, however. This shade does NOT come with rope or anything to help you secure it, so you have to buy your own hooks and ties separately. Additionally, the material stretches A LOT after it sits in the sun for a bit, even more if it gets caught in a wind storm. Now that the shade has stretched out, it’s too big for our space and sags low enough in the center that my husband can barely walk under it. We plan to run twine underneath to help hold it up. Had I expected all of this, I would have ordered a smaller size.
