Using the BoonBoom Controller is easy. Just hold it in your hand and press the button near the LED gauge to transform it into a bow and arrow. When playing with the DX Byun Byum Mach Robo, simply push and pull the parts to change it from car to robot mode. Remember to keep these toys away from small children who might put small parts in their mouths. Also, avoid getting them wet as this can damage the LED and the moving parts. To maintain them, use a dry cloth to wipe off any dust regularly. Have a great time playing with your new toys!
