Using this B-Fighter Kabuto set is a breeze. First, take out the Command Voicer and the Insect Commander from the box. You can insert the Input Cards into the appropriate slots to activate different functions. When you speak into the Command Voicer, the voice - recognition system will work and trigger corresponding sound effects. You'll also hear henshin and attack sounds, just like in the show, and even the TV theme song. As for maintenance, keep the set away from water and excessive heat. Don't use sharp objects on it to avoid scratches. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. And remember, this set is for indoor and personal use mainly.
