This circuit is very nice to ride, especially to play! cars are very robust, they do quite frequently the circuit to go kick in walls and furniture. The looping is the main part of the circuit, where we can go faster. The circuit is in good order, by cons not too suitable for small children because they often pounds Relationship off the road, and just tap the barriers plasticized cardboard which eventually tear. In the end very good product that still need a certain level of control.
