Using the Megawrex is super easy. First, make sure the batteries are properly installed in both the truck and the remote control. Then, turn on the remote and the truck. You can use the buttons on the remote to control the direction and speed of the truck. When playing, try to keep the truck on flat or moderately uneven surfaces so that the Terrain Action Tires can work their best. Remember, each truck is sold separately, so if you want to have a battle, you'll need to buy more than one. Colors and decorations might vary, so don't be surprised if your truck looks a bit different from the picture. As for maintenance, after each play session, use a dry cloth to wipe off any dirt or dust on the truck. Store it in a cool, dry place to keep it in good condition. This toy is suitable for kids aged 4 and up, so adult supervision is recommended for younger children.
