Rated 5 out of 5 by Anonymous Great for arm pump
I'd been getting bad arm pump on long descents so thought i'd try one of these.
Sorted it out fairly quickly and I haven't had arm pump since!

My office colleagues also love to play with it and we challenge, beating our own records. It's great you can see results using this one.

Rated 4 out of 5 by Anonymous i bought one of these powerballs going on the strenght of all the positive reviews! OK they aint bad! its one of those things that you can leave on the shelf for weeks then pick up and be at it for hours! after you get the initial hang of it they are pretty easy to manage! one thing i would advise any would-be buyers is save yourself a few quid and buy the one without the digital counter.. not only do the readings never make any sence it also makes the ball more bulky and harder to grip.. i dont really see any point in having it there.. well thats my opinion im sure others will differ!!!
