This toy is aptly named. It really is very quiet and the bullet is one of the smallest we've ever seen. Not only that, but the pushbutton control sets the two speeds from 'Wow that's fast!' to 'Holy Cow, that's even faster!' It's got a soft rubber cote that feels great even before you turn it on. Our only concern about this toy is: It might be too powerful for some users. So only buy it if you're sure you want a tiny dynamo to play with.
