Can Be very Noisy
(which is actually quite a nice thing)
The Gyroscopic Powerball from powerball-gyros.com has to be one of the most intense and addictive sports equipment I have ever used.
Once you get up to a stagering 15,000RPM it makes you feel as if your arm is going to fall off.
This is a very good muscle workout, and I would reccommend it to anyone.
