The great weakness of the Carrera models lies in the battery area. Despite warnings, it's what happens the children forget off the vehicle. To keep the battery then mostly defective and can no longer be recharged. Replacement battery costs again measly 16-18 EUR. For us, it is happening now for the second time, despite alleged automatic Auto-off for the RC police Porsche. A great pity that is not even brought a workable solution here. Otherwise the vehicle is OK but needs a very smooth flooring otherwise it bumps on the surface of rum as too easy and poor suspension. Not for the apartment as quickly.
