Using the HEXBUG VEX Robotics SwitchGrip Ball Shooter is easy. First, gather all the 140+ snap - together pieces and start assembling your blaster. It should only take a few minutes. Once assembled, fill the loader with the 11 included balls. Then, perform the launcher’s pumping action to shoot the balls over 20 feet. Remember, this toy is for ages 8 and up. Keep it away from small children who might choke on the balls. After playing, store the toy in a dry place. If any parts get dirty, you can use a damp cloth to clean them. Don't use harsh chemicals as they may damage the toy.
