Bests & Worsts Reviews from Amazon

I purchased this item thinking it would do what it said it would. When it arrived I was totally shocked! It came in a small bag, it was very thin and did not do the job it stated it would do. I wanted to return it back to the company, but to my surprise, it was up to me to pay again for shipping! Thirty Dollars thrown out the window. I would have been better off going to a Hardware store and purchasing plywood for better support.
