Using the DX Leon Buster 50 is a breeze. When you want to see the cool gatling gimmick, just simply pull the trigger. It's that easy! If you have the DX Tega Sword (which you need to buy separately), you can combine them to make the Tega Sword Blue. As for maintenance, keep it in a dry place and avoid dropping it. Also, don't try to force the parts together when combining. Just follow the natural way of fitting them, and you'll have a great time with your DX Leon Buster 50.
