Product review (4 stars): Easy to install, but folded during shipping causing creases that don't come out.
This was easy to install and meets my needs well.  The only complaint (and keeping this from 5 stars) is that when it was shipped, it was folded and thus there were some creases in the gasket.  Despite my attempts to remove the crease completely, I have not been successful.  So, there are two areas that I fear are not sealing as well as they should because of this.
