1st problem: the puzzle falls apart when rolled up.
2nd problem: the plastic cylinder deflates.
3rd problem: when assembling the puzzle, the pieces stick to the material and cannot be moved without falling apart.
4th problem: it collects all the dust and pet hair in the house and cannot be cleaned.

Definitely not worth its money.

It is very good and serves very well if you cannot dedicate a space until you finish the puzzle. Of course, its price is a bit steep for what it offers.

Very practical. It keeps the pieces in place, but it requires attention so that they don't scatter when you want to remove the puzzle for framing, for example, as the adhesive holds it and doesn't let it slide easily!
