Well, the price is already too high for a normal felt-mat and an inflatable roll with Ravensburger logo ... but the functionality I'm thrilled! One can well puzzles on the felt, there is now nothing. Have previously briefly about it ironed on the wrinkles around it to straighten something. A 3000 piece puzzle fits very well to this size, rolled up is the puzzle in 30 seconds. With such a large jigsaw puzzle, however, a second person is helpful nice tight wrap everything to the role.
When rolling out later everything funkioniert well, one only needs to emphasize times with the palm over the puzzle to all parts to smooth again.
My conclusion: super practical!
