Review on Puzzle Roll Mat PiecesPieces Inflatable by Jack Harrell

I actually found using this pad made the puzzle difficult to put together. With no dimensions on the pad itself, it's really useless. The description and pictures appeared to show printed dimensions that could be used as a template. Yes, it will keep pieces from slipping, but it will cause them to stack up. I had to use a tape measure if I wanted to confirm and adhere to the correct outside measurements. Not worth the money in my opinion.
