Have you ever noticed that it’s harder to turn a spinning wheel than one that is not spinning? The Gyroflex takes advantage of this gyroscopic effect to bring exercise to your arm. It’s kind of like a stress/exercise ball on steroids. Just pull the cord and try to hold onto the ball for more than a minute! You can get the Gyroflex at Gadget Universe.

I have one of these things! but its a power ball brand. It can be pretty entertaining especially at first and the powerball displays the RPMs and some other info as you use it.
