Gravitrax

Über Gravitrax hat sich meine Tochter (7) sehr gefreut, sie ist auch gerne mal einen ganzen Tag damit beschäftigt. Diverse Aufbau/Erweiterungsmöglichkeiten. Wir sind alle schwer begeistert. Auch ich bin Stunden mit ihr beschäftigt. Jede bisher gekauft Erweiterung könnten wir mit Spass verbauen. Absolute Kaufempfehlung.
