The only problem we have found with this canopy is the lack of sticking on the hook and loop tabs that the walls are attached with. We live on the coast, so there is a lot of wind. The tabs are only stitched once. They pull off easily. We have had to remove the walls several times because of the wind. If the walls are not removed when the wind picks up it becomes a kite and rips the poles and tabs loose. But we are using over the hot tub when working out and love it when it is all together. Perfect for keeping leaves out of the hot tub and gives us some privacy from the neighbors.
