Using this Gokaiger Mobirates is a breeze. Just insert the Ranger Keys, and it will play the corresponding sounds. The new Gokai Galleon key, once released, can also be used in the same way. When handling the keys and the Mobirates, be gentle to avoid any damage. It's important to remember that it may not work well with past DX releases, so don't be too disappointed if there are compatibility issues. To keep it in good condition, store it in a dry place away from direct sunlight and moisture. That's all you need to know to enjoy your Gokaiger Mobirates to the fullest.
