Save your money! This sun shade is nothing more than a poor quality tarp that you could buy for a few bucks at your local home improvement store. I bought this sun sail to replace my old sun sail that was approx 10 years old & starting to show its age. However, the old shade is still in better shape. This was a cheap, crunchy plastic material that looked and felt awful. I cannot speak to its ease of installation, but it does not do a good job of blocking sun as it has a very see-through open weave. Water resistance?? I guess since it is plastic. But I cannot imagine it holding up to the elements for more than a week or two. I thinks few weeks in the breeze would rip it to shreds. I am an avid Wayfair shopper & am usually very pleased with my purchases, but this is hands down the worst Wayfair purchase I have ever made! Thank goodness for free returns!
