At Christmas was our son, who else but rather with an XBox (which we do not have, but the relationship and friends) would like to play or I-Pod, the Fischertechnik Super Cranes. Within 3 hours at a time he had built up the great. Had his old man ask only once, otherwise he has bitten through alone. Is mighty proud of it and plays with it. Alone There is a perfect score. As always, Amazon perfect score for fast delivery. Great as always.
