These innovative bright coloured remote controlled cars are rechargeable using the included docking station, meaning no more changing or running out of batteries. Each car operates on a separate frequency, so all can be used together without clashing of frequencies. Ideal for early control skills, the remote handsets feature a 2 button control for forward and reverse turn. Use indoors and outside (on a level terrain). Set includes 4 cars and handsets, docking station and power adaptor. Age: 3 years+.
