Since I rarely get to puzzles and corresponding need for a single long puzzle, I ordered the role, so the puzzle sometimes may be a few weeks in the area and does not take up space in our small apartment. The idea and the grunsätzliche handling are also okay, but at every assembly and disassembly roles I am annoyed, because everything does not work one hundred percent. I can think of at first two suggestions for improvement, and I wonder if the product developers have tried their product at all myself. 1. The fabric is relatively loose on the inner part and you can not tighten it so that the pieces do not rest properly fixed. I always fly scattered puzzle pieces out of each other or even completely. Could you hook the cardboard roll somewhere on the substance or mooring otherwise, you could wrap the whole thing all at attention and the problem would be solved. So, as it is now, you best need 4 hands to hold the fabric on the whole length at the same time, while bundling him. I've already tried the substance at the edge stick taped to the role, but that did not stop. 2. The cardboard tube, which is to take apart in the middle (probably so you can stow them better when it is not needed), is also in the rolled-up state apart again. They can not fix properly, it is only loosely fitted into each other. That can not be so difficult, because a better solution to be found!
