We bought these robots collection together with the Axiom station of Wall-e for Christmas. This is a pure merchandising products quality. The robotic vehicles are schwerpunktstechnich made so bad that they can be used in the associated game station barely. You roll poorly and fall due to the high center of gravity to constantly. They can really only as "Stellhinchen" the children's shelf filters (advertising aspect). Games can thus certainly not. So therefore my advice: DO NOT BUY.
