First the positive. Materials are good quality and works great for privacy. If you want to keep bugs out this may not be for you. The corners where the enclosure meets at the ground level cannot be secured completely. At least we couldn't. The wide straps don't compress against the trailer enough and when the slight wind gets through the enclosure pulls up. The long piece that goes against the trailer to the ground would not stay up. We tried several different methods and it would not work. Tensions bars would not stay in place. Stakes pull right out of the ground. Some of the straps to put the stakes into to pound into the ground broke at the first use. No way to anchor the bottom of the walls to a cement pad. So, unfortunately, we have not had a good experience with this expensive purchase. Also, with the door and the zipper zips from the bottom up. This is very difficult to get in and out.
