The quality of the "Jumbo 17571 - Original Rummikub Classic - with Hourglass" is great.
The stones are rough and sloping on the sides. So can be captured well by a smooth table surface. The back of the stones is decorated with a logo and the Rummikub Rumikub face.
The Aufstellbretter look good and are made of plastic. You could be a little heavier, and thus be more stable, but function properly. Before the first game the pedestals must be clipped. That's a little fiddly, but needs to be done only once. Then you fold the feet and an easy out.
It would be nice if even a small bag would be accompanied for the stones, so jumbled loosely around in the box.
As I said, a great game in a great design.
