DealExtreme are selling these "LED Power gyro wrist ball things for just under USD $8. They seem to be cheap clones of NSD Powerballs. The NSD Powerballs are much more expensive, though. Apparently, these products can provide some RSI and wrist-strength benefits. One of my friends got one of the cheap DealExtreme versions, and says its a novelty at best. I think I'd probably be much better off spending $20 on the Captain's of Crush no. 2 gripper (which I wrote about here), now that I can close the no. 1. Still, I'll give it a go some time.
