Two complaints: 1) The product is packaged too tightly for shipment and it is very difficult to remove folds and creases. You need to put it in a sunny room for a few days to straighten. 2) Adhesive strips are too small, weak and poorly positioned. The sum of these two complaints is that you need to see a professional. As a result, you'll have to use extra glue and/or staples (the latter doing the job amateurishly at best). .
