Only joy, then came the rage ...

When it arrived fairly quickly at me, I was really looking forward. But these went quickly lost again after a few minutes.

Assembly:
In the pictures they found it as easily back, but in reality it was a different story. These red rolls should be simply screwed into each other where I would soon rotated by. Back to the top nothing seemed to fit into each other, after use of force, it was possible to screw these things to a large roll together. When I then looked at me all the more closely, I discovered black spots on the cylinder and was a little disappointed.

Schön is true that the puzzle no longer slip on this "cloth". But when once they have been placed, they are difficult to move or separate from each other.
After I had completed the part of my puzzle, I wanted to try, whether it with the rolling technique really works. After all slipped so so nothing. Wrong! I have slipped all the puzzle pieces apart again and I was able to do it all over again.

Actually, it should be practical, but for me it was a letdown.
