PowerBall Sports Gyro Exerciser Various

This item is a great item that is fun and works out your arms so great that it feels like they will fall off. Although when i bought the item i thought that i was buying the highest end gyro ,Powerball Blue, with speeds of up to 18000rpm and 40lbs resistance. This is simply a cheaper gyro that they applied blue lights to and called the powerball blue since it only has 32-35 lbs resistance and speeds up to 13000rpm. So make sure you know what you are buying because it was a big mistake for me

As the title suggests, this thing works well for strengthening forearms and fingers and helping with climber/tennis/armwrestler elbow. The LED light is cool at first (useful as a nightlight) but annoying if you''re trying to exercise inconspicuously. Some reviewers have referred to this powerball as a toy and I would tend to agree. It feels cheap and after a short while it starts to develop signs of wear like squeeking, rubbing, and just general friction-derived noises that also annoy. It''s like buying a new bike that already has a bent rim, worn brakes, and bad bearings. This model is said to retail for $40, for this price I would definitely get an NSD brand powerball. They start at $25 and have much better quality gyros (smooth as silk). Take home message, this powerball will get the job done, just not with the quality you would expect and could get with a better powerball (www.nsdpowerballs.com).

Great product

There''s no end to the number of activities that involve hand, wrist and arm movements. Golf, typing, boxing, baseball, basket ball, arm wrestling. I box and practice MMA, and I love this thing. It''s basically a gyroscope inside a tiny ball, you start it, via the string it comes with, or with your hand (a bit difficult)

After reciving this product I went through many stages with it, I couldn''t use it, then I loved it, then I disliked it, and now I love it again. This is because it takes a bit to get used to the movements involved in accelerating the gyroscope, but once you get the hang of it you can really get a good work out for your hand muscles, and your wrist, and also your arm. A full speed dynaflex has to be held to be believed.

However addicting, the string used to start the dynaflex will probably break before you manage to learn how to start it manually. The product comes with a mini CD that has a nice video explaining how to start and use it, and mentions that a manual starter can be purchased (but not available on amazon) But with a little snipping, any shoe lace can be used to start this neat little machine

It''s like the nintendo Wii, I broke this machine''s string because I was SO addicted to using it

I bought one after seeing a friends. Mine was very hard to spin up. Had to use a string pull to get it started. Then it started getting harder to keep going. Contacted dynaflex about replacement, service, advice etc. All I got was you must have abused, dropped etc. Very poor communication style with all caps and misspelled words on top of accusations I was responsible for the loss in performance.

I enjoyed using it the 30 to 40 times I could keep it going.

A friends powerball pro with no lights is much easier to spin up and has been working for hundreds of spins. Maybe I got a lemon but the customer service experience was bad.

So I got it today. All the people who said they couldn''t get it to start, or that they have a lot of difficulty have some problems of some sort. I think the main problem is that they don''t experiment, and like try to do the same thing over and over again, which obviously will not work. So I played around with it for about 5 min. After that time I was able to start it using the string and get it going to very good speeds, got some good time on it at that time. Tonight I played around with it for another 10 min so that I wouldn''t have to take a string around with me. Now after about 10 more minutes time I can start it up at a success rate of about 80% by hand, no string, no special surface, just the ball in one hand and the other hand. Works well, can''t say anything about long term effects, but I do know another pianist who uses one (we''re really prone to hand and wrist injuries) and a martial arts guy who have both had good experiences with it.
