We have specially purchased the protective film, as it is slightly wider than most other films. The build quality is OK so far, it's just a film with the edge and a few attachment points, here the performance is as expected. However, the sides fold in a short time and hang left and right down to the front, which firstly does not look good, and secondly offers the folded places also no protection for the seat. I solved it with a sturdy plastic piece that I glued on top of the full width of the back of the protector. That's why only 4 stars but with this little rework do the protectors again their service.
