Between the Spinning Top and Yo-yo!

Much less revolutionary than it seems certainly this friendly object some kinks. The rotor remains permanently accessible (no hull or protection) and can cause serious burns. So for the handling it is better not to have too big hands, and passing from one hand to another is risky.

The possibilities are very limited gestures, small circles of the wrist, and it is much more a nice little gadget that any weight machine or physiotherapist. I even think we should be able to create acharnant channel type carpal pain rather than protect themselves because heavy use quickly leads to the typical pain of "gamers" of former addicts who handles manhandling fingers and joints.

I do however regret my purchase, despite the grim side of the launch lace. This model does not nice lighting effects such as model "neon" and yet it is a real plus to make it into a completely useless but so perfectly original gadget. Small detail the meter does not automatically triggers ... that I think I've been around.
