Happy with the product and that it came with the hardware for attaching. We decided to use 4x6x12 poles for more support. The only thing that was a concern were no directions for the placement of the  poles. I set them 6 inches wider than the shade demensions and slanted the poles 20 degrees.  I still have a sagging in the middle. I am thinking that the pole spacing should be at least a foot and a half wider, this will ensure that the shade is tight. You will have to water proof the material otherwise it is porous and water will pass through.
