i bought this about a year ago and its awesome, within seconds you feel it working all the way up your arm. it even works your upper(bicep/tricep)arm building dexterity. the gyroscope spins faster as you move your wrist faster so it will provide more resistance as you get stronger.i cant think of a better way to build strength and dexterity.its only down side is due to the fact that it does not help at increasing finger speed, due to the fact that you don't move your fingers. if your looking to improve you r dexterity or finger pressure its awesome.if you go to www.powerballs.com they have some great videos.

I have no idea where the glowing reviews for this toy come from. Are these kids or adults?
I have had one of these for years and have yet to figure out how it is still marketable. My fist weighs more than this toy which spins at rpms so slow it has no discernible centrifugal force. The ads I read before getting mine convinced me the thing was capable of miracles. An 18" piece of shoestring is provided to get the internal "gyroscope" spinning at very low speed when, in fact, it would take a machine to do anything of the like. The entire thing is made of plastic which explains the lack of worth. There is not enough mass to do anything for me. Can an ant roll a bowling ball?
I can hold an 8 lb weight out in front of me if I want to tire my shoulder, do curls for my biceps or pushups for my triceps.
I have plenty of grips and other finger exercise tools.

You Better Start Doing It Right!!!

Comments about Finger Fitness Dyna-Flex Power Ball:

These exercisers DO work - so if you aren't feeling anything becoming more intense you DO NOT HAVE THE TECHNIQUE DOWN PROPERLY.

I felt the exact same thing, at first. But once you discover the proper technigue of slightly "rolling" your wrist in a circle away from you, and then back, these will build up so much power that you can barely hold on to them. I use one constantly for limbering up my hands for gigs.

HINT: Keep the base of the ball centered over your palm. If you don't have the center lined up it will never work. Pull HARD with the string and start with a circular motion. It feels like it isn't doing anything when you start - but keep rotating your wrist. If you are doing it right, it will start to feel weirder, "heavier," and you'll begin to feel the rpm. Keep rotating your wrist - the dyna-flex will teach YOU how to make it work. They are tricky to use, at first. But once you know how, you lean when it's "working" and when you have to start over, again. I can't always get mine to start working on the first try either, so remember that.

If you never feel any power from these - then you haven't discovered its secrets. They're great for your hands. What are you waiting for?

Keep trying.

Worthless

By leesware

from NC

Comments about Finger Fitness Dyna-Flex Power Ball:

I don't know who is giving this thing a good reveiew...it is absolutely worthless. Maybe mine is defective and it is a good product but my experience is that it simply does not work. I'm moving on to other products.

Comments about Finger Fitness Dyna-Flex Power Ball:

Some people think that this device is hard to start and noisy. 1) Being that if you are a musician there should be no problem with noise, because from the years of rockin', you deaf, problem one solved. 2) If you use the pull string or a docking station, its even easier to get it up to speed, you can either get the docking station separate or together, the Dynaflex "Gamer" has it included and is the best bang for the bucks. I find this to be the funnest and most addicting hand, forearm and shoulder strengthening device out there, period.

Amazing Little Machine

Comments about Finger Fitness Dyna-Flex Power Ball:

I love this device. It takes a little while to get the knack for it, but after a dozen unsuccessful attempts, I got it spinning, and it is just an awesome exercise for the wrist, fingers, and all the joints. I highly recommend it for all musicians.

Cons

      Comments about Finger Fitness Dyna-Flex Power Ball:

      I have small hands and wrists. This is ideal for strengthening all parts of the arm from fingers to shoulder. It's easy to work with and small enough that I can pack it in my bag to take it anywhere. I've had it less than a week but the difference in strength is obvious after only a few workouts.

      This Rocks

      By Stratdude1313

      from mars, Solar system

      Comments about Finger Fitness Dyna-Flex Power Ball:

      My sibling just got this for christmas, and it works great. I've really been using it on my right hand to get picking strenghth up, and its obviously working. I give it an 8 on features, because once you get it spinning, you have to keep progressing in speed, or it will stop. other than that, this thing is perfect! 10/10
