The roundabout fascinates young and old. I was able to test several times since the purchase already :-) However, it is also processed like a toy. The bearings are not particularly stable, and the metal ring on which the bearings are mounted, is interrupted. Ie, it is seen that the ring has been bent in one piece. The interruption means that the seat of the bearing will bend over time, causing the flywheel can then no longer so precise turning. But still. A very valuable toy, because it raises questions with young and old, and thought-provoking.
