This is one of the two Kamen Rider henshin belts that I got from Amiami. Unfortunately, this belt has some mechanical problems. For the henshin sequence, the slider on top is supposed to be pulled out to the side and then when the blue knob is triggered, the slider slowly retracts making the ball in the middle spin. But on mine, instead it just pops back without spinning the disco ball thingamajig. Being that this is the only feature on the toy and the fact that it doesn't work sucks.
I can probably open it up and tinker with it to fix it, but possibly break it as well. I will shoot Amiami an email to see what they say, although I think I will just get a nicely put "Too bad" reply LOL
