Not worth the money.
A very useful helping tool - I would prefer it in the main box. I'm glad that I ordered it together with the game itself, since I doubt that I would have bothered with another ordering, which would have meant another transport of a small box from the Netherlands to Austria.
This thing is very satisfying, and kids love manipulating it. It greatly improves their interest in a way I wouldn't have thought of.
Super addition - great for managing the balls, which are small for adult hands - and a really clever but simple design.
Definitely a must as it loads much quicker. My son loves this !
