text: Does not lay flat. Creased beyond usefulness.
  
  I SHOULD HAVE RETURNED THIS PRODUCT BUT THE RETURN WINDOW RAN OUT. The liner comes folded and does not lay flat. I thought that if I left it out, the material would eventually relax and become flat. It has been out a week and it I still all rippled. Why would the manufacturer not ship it in a tube or wrapped around a tube!!!! This liner is useless. What a joke. Do not buy.
