Perfect for our very small patioThis RED sail shade is very thin and cheap. Don't invest in this product as it doesn't block the sun at all. I purchased the gray one from Home Depot and it's so much thicker and better. You can see the contrast between the two. The red one is the one I'm referring to, as it's poor quality and probably won't withstand the winter. I'm guessing sticks will poke right through it. Very cheaply made. thumbs down!The gray one is the one I bought at Home DepotDefinitely not as “right triangle” as they say. The second picture advertised is very misleading and it looks a lot more like the 4th picture if anything, so it doesn’t shade nearly the amount as I had hoped.Got it thinking there would be a 90 degree angle in the corner, and it’s much closer to a 45 degree angle.Other than that it does the job, just not what I was hoping for.The shipping was late. The vendor prints the shipping label when you order so that it looks like your items ships. But in reality it took a week for the item to actually ship, meaning given to the shipper. Then UPS had issues.I temporarily setup the sail shade to get an idea for anchor placement. There is zero room for deviation in the anchor placement if you want the sail shade to be tight. In the temporary setup, it did provide shade.Bought a right angle sail shade last week and so far I love it. Yep, it does stretch a bit so I've had to adjust the tensioning turnbuckle a few times so take up slack, but this is easy. It rained hard the past few days and water does go through it no problem. The rain accelerated the stretching I think but once again, the turnbuckle takes up the slack well. I am sure you all know that hardware doesn't come with these sails (at least the one I bought) but I am fine with that. All in all, great product.This is an isosceles triangle that provided the perfect dimensions for my application. I wanted to provide a little shade for the patio door as to not interrupt my umbrella or picnic table. It worked perfectly for me and this particular corner of my patio. I did however have to build a bracket to extend the one side slightly and to also provide a place for a hanging basket of flowers. This was an inexpensive solution for me. I like the color and the material.The polyethylene is strong, flexible and easy to work with. Quick addition of shade and deck-side appeal. Well worth the $$$.The shape just whT I needeed
