Product Description
Only slightly bigger than a tennis ball, the PowerBall/Sports Gyrociser is an amazing power ball that works on your movement alone; there are no batteries. Once you have started the Gyrociser spinning, you simply rotate your wrist in either a clockwise or anti-clockwise direction. This creates a gyroscopic force which exercises the muscles just by the power created. By picking up the resistance, you can increase or decrease the speed of the inner ball by muscle control alone. The faster you make the inner ball spin, the more the resistance, and the heavier the Gyrociser feels. This in turn makes you grip harder. You can make the PowerBall/Sports Gyrociser spin at up to 8000rpm. You can obtain this speed by strength, co-ordination and control, making the Gyrociser an excellent training aid for anyone who needs to gain strength in their fingers, hand, wrist, foreamr, biceps, triceps, arm and shoulder muscles.

 Very addictive December 30, 2008
Paul Percival (Cambridge, England)
I have had this for less than a week but spent far to much time playing around with it. For such a simple thing, it is incredibly addictive! I wish I had gone for the type with the rev counter and extra fun bits simply so I could set targets or whatever... Otherwise, great product.

just to be aware people. i bought this for my dad for fathers day. but in the instructions it said not to use if you have a heart problem, so i was very dissapointed when he couldnt use it!! also it is very hard to get the gyro working.

After a week of using the ball for about 2.5 minutes on each arm per day I have already grown muscles in all parts of my arms... its like magic!!
Extremely fun and addictive June 10, 2008
Ian (Wales,UK)
I have heard how good the powerballs were but i didn't think they would be that effective however i thought i would give them a go it's only a tenner at the end of the day.
So it arrived in the post opened it up started spinning it with the cord i messed up first couple of times felt quite weird keeping it going but i got the hang of things and now i am completely addicted to them i spend at least 15 minutes a day using one and i am actually quite surprised by how effective they actually are.
I would definitely recommend these you will see and feel a difference within a couple of weeks

To be quite jonest this powerball is awful. It is hard to get going, and when you do it does not spin very fast and is not beneficial.
My advice is don't wast your money!!!
