4 out of 4 found this review helpful
1) Dynaflex is the best. It is totally new fun and experience
2) "Powerball" is the best of Dynaflex (generates the most pressure and requires the biggest effort)
3) The only other model you may want to get - it is the same "Powerball" with spead measurement display. It is optional though...
4) After I showed it in our office, couple of people purhcased it same day!!!

I bought this item to start training for bowling. It's been a couple of weeks of using the powerball, and still no bowling, but the powerball itself is amazing. My biceps, triceps, pectorals feels as if i've been working out a lot. You can use this while on the computer, altough is not easy to type with only one hand, while walking from work to the parking lot, or while watching tv.
The only thing, is that it's pretty hard to start it up without the attached string. I lost mine and using an adapted shoe lace to start it while i'm able to do it with only a finder or by hand.
I really would recommend getting the speed meter. I bought it later and is really nice and addictive, cause you always try to break your own record. Also you can use it to do comparative plays with friends.
Really recommend this.
