Using the BoonBoom Hacker is easy! First, use it to replicate the patterns of Boonboom vehicles. Then, insert it into the Boonboom changer (you'll need to buy this separately) to make the vehicle sounds. If you want to replicate a new pattern, just press the Tokoon figure in the center. There are some codes you can try, and you can find the list on the provided link. As for shipping, it's free if you're in the USA. Keep the device clean and away from water. If you face any issues, contact the support team. Have fun using your BoonBoom Hacker!
