Review on 12' X 12' X 12' Beige Sun Shade Sail Canopy With Commercial Grade Hardware Kits - For Patio, Garden, Outdoor Facility And Activities By Windscreen4Less. by Viswanath Badasz

These are really good so far. I purchased 3 and they overlap slightly to block sun on one side of my house. They filter the light well enough to not heat up the windows or walls nearly as much as without these. I would say an easy 40 degrees or so cooler on the window glass on my interior after installing these.As far as durability goes, so far they have been great. Although, this is going to be the first summer they will be in. It will be interesting to see how they hold up in the hot California sun all summer.I tend to not update these reviews, so honestly the summer heat and sun will be the ultimate test! But for the price I paid for these. about $25 each, you really cannot go wrong.The materials and design are built sturdy like other reviewers have stated, it's true! Nice metal rings with strong stitching and the fabrics they use for the main sail and the corners and edges are all made with strength and durability in mind. No issues with build quality so far.Make sure all of your mounting points allow you to pull the corners of the sail very tight. I am using a 750 lb test paracord to string these to 8 inch galvanized eyehole lag bolts into a clay hill side, and roof eve screws with anchors and brackets (from a kit for this on amazon), and you can pull the paracord super tight. I have one paracord run going over 20 feet and there is very little sag I have pulled it so tight, and it is holding just fine! These look pretty ratty when they are not pulled tight. But once tight, they look really nice like at a high end resort pool area or something. Very cool, literally!
