Unfortunately, the product is damaged. I had the "crumbs" namely through the film noticed before unpacking, but saw no damaged area. A small, unobtrusive I have also taken into account (for the price and the Prevention of Back Schickens), but during installation I discovered two more. All is not great, but I'm afraid that the moisture in the bathroom and the inner material of the toilet seat complement not advantageous. In addition, my Befestiung not appears to be designed for "long life", but well, a toilet seat is also no "long life" -Anschaffung.
I have decided to appoint replacement once it arrives and is without prejudice, I will correct the assessment on 4 stars. (Hope that it will work!?!?)
