I can associate myself with the other recessions only partially. My son is now 11, goes to high school and is for scientific things just to inspire. The circuits can plug together every child but I hardly think one will understand what happened there or learn something. I will not play with the box alone my son. Since I take rather then the weekend by 2 hours and we create two experiments which are then also really understood. Since I myself have studied electrical engineering, I can explain to my son. The packaging is really bad and I think you can really expect more at this price. The components are mounted on small vehicles and can only be replaced when they go badly broken. Here then always original spare at Busch must be ordered. My old cosmos electronics box from the 80 there was really better. The parts could all get in, for example, Conrad. The module is plugged on the very stable. Unfortunately, there is no longer the case so. Currently there are from the cosmos XN1000 and I think that would be the better choice was. What I liked a lot the expandability. Whoever sees that it is right for the child can expand the system at least twice.
