Review on TANG Sun Shades Depot 10' X 15' Rectanlge Waterproof Knitted Shade Sail Curved Edge Red 260 GSM U*V Block Shade Fabric Pergola Carport Canopy Replacement Awning Customize Available by Duane Mann

I have used several different shade sails in the paste. We like them because they are an easy way to add shade. I previously owned the mesh type and they produced good shade. This time I decided to try a waterproof shade. The problem is when it rains. Since the sail is waterproof and there is no support in the center of the shade, water builds up in the shade putting a strain on the tie lines which have to be tightened each time it rains. There is a large water puddle sag in the shade and during a windy, stormy rain, the shade blows around and water spews everywhere. After the rain, I have to use a broom to push the water out of the sail. So, yes, the shade works as advertised, but needs some thinking about the water build up. I plan to put some grommets where the water builds up to allow water to escape.
