I've seen these on CRC and wondered what they were for. I actually found out this week- it's an eccentric and quite heavy gyroscope inside a case, which you can force to speed up to around 12,000 rpm by moving your wrist in the right way. As it speeds up the gyroscopic action and the sheer inertia of the gyro become harder to resist and you find your hand and forearm aching like hell. It's brilliant fun and fantastic training for cycling, climbing or anything that needs a strong grip. And it self-generates a bright bluey-green light from the LEDs inside too. I want one!
