Quality construction, seamless body, no removable parts. The controller has 2 buttons, one for forward and one for backward (like doing a reverse). With the latter, you can also steer the remote-controlled car. It has an on/off button on both the car and the controller. The range comfortably reaches 3-5 meters. It moves smoothly even on low-pile carpets! Especially for young fans of the series, if you have a second one, you can have some really fun races inside the house (it withstands collisions with sofas, etc)!!
