Unique size which is why we purchased. Appears to be efficient wind sail but yet to be tested (we are in Fla). Solid hardware included. I bought additional hardware only because of a unique configuration I am using it for over grilling area under a screen. Hoping it serves us well!

[This review was collected as part of a promotion.] The sails were put up with a team effort in our front yard deck area. A few days after they were up, we had rain and quickly learned our errors. We had so much pooling on top which showed that they are fully waterproof. I waited about a month, then placed a second order for our backyard sails. I love having the choice of so many colors.
