Dynamic, exquisite, absolutely gorgeous! The extraordinary new Powerball Signature, with its sapphire white light neon rotor revolving within a subtly smoked shell, is truly a design classic and will exceed the very highest expectations of Powerball fans all over the world. We are talking silky smooth movement here!Put its rotor in motion, and the ball instantly comes alive with Gyroscopic force - a sublime yet pleasant resistance to the movement of your wrist and hand, and one which grows in its intensity as the speed of the rotor builds...faster and faster...up to a point where it is thrashing and jerking furiously, literally exploding with inertia and almost impossible to control!This limited edition gyroscope has a top speed in excess of 16,000rpm and can generate over 40lbs of resistance on the hands and arms as it spins (which is quite extraordinary given that it is just the size of a tennis ball and weighs under 300grams!).

#Greater golf strokes (2009-06-16) I have had the Powerball for several weeks now & already am over 10,000 rpm. The reason I bought the Powerball was due to an ongoing issue with some pain experienced in my wrist due to prolonged periods of sitting at a computer. The benefits in the reduction of pain are so dramatic to the extent that I no longer experience the pain previously felt. An added bonus has been that I now feel increased strength in my forearms which has benefitted my golf game dramatically. Although I initially felt that the price was quite high for what I felt imagined ...

#Good fun and hard! (2009-06-04) I personally find using this difficult but that doesn t deflect from the fact that it is loads of fun and an interesting item to bring out in company to boot!

#Full satisfaction (2009-06-03) It is wonderful!. I am 80 years old and I am still unable to reach 10000 RPM but I keep hopefully trying to increase my maximum speed .

#Powerball white (2009-06-01) The ball can take some people a while to get the hang of but once you have it, there s an addiction that takes over. I ve had a couple of blisters but they only lasted a couple of days. You can feel the ball working on all sides of the forearm. It s a great party piece too. One of my Son s is obsessed with it working the way it does without batteries and his friend can t get it together enough to keep it going. The rivalry is fun to observe and funny when they re told to change hands. It s amazing how our left hand isn t as coordinated as the right. ...

#one day toy (2009-05-12) It s good, really good but after few days you will lose interest to this product.

#Powerball ! (2009-07-01) Amazon had all the information I needed before buying this product, besides the information on Amazon the powerball website contains a lot more information. . bought two of these both for my parents !! a great buy indeed. . the only drawback is that if these balls spin off your hands. . . and fall. . you will mess up the gyro balance and will have to live with a noisy powerball for the rest of its life !

#It s a fun product (2009-06-21) It s a really good little excerciser and does what it says on the box but it may be worth purchasing the next model up. The one I tried before I bought this one had a built in rev counter and this one doesn t which is a bit of a loss actually. Being able to see the speed makes it far more competitive.

#Not bad (2009-06-13) This isn t bad at all! I have wrist problems, and it is for sure that using this regularly will improve my wrist strength!! Probably not ideal for toning arms or anything else. Although your forearms will get a decent workout!!Bit annoying how i chose to get the one without a counter, because my brothers does, and you feel there is more purpose when you can see your speed!!

#Fidgeting fun (2009-06-12) Picked up this version of the Powerball because I had been looking for a one for a while but they seemed to be hugely expensive for a spec purchase. The amber is apparently an unpopular colour, so was cheap even for the basic model. I mainly wanted one for the therapeutic aspect, as I have some long term muscle damage in my left arm and I have to say I have been pleasantly surprised. Although keeping the spin going with your off hand isn t the easiest thing in the world once you get the rhythm it does what it says on the tin and provides low impact exerc...

#Powerball (2009-06-04) This power ball is quite cool, good exercise & great convenience. highly recommended, you will never imagine its impact but after giving it a try! However, bit noisy!

#Love it! (2009-06-18) One of the best exercise tool I ve came across. It s not worth to buy the standard one, you need to get this one with the display & counter. Also check the powerball official forum for great tips & tricks! There s even opportunity to become the powerball world champion !

#Gyroscoping healing powerball style (2009-05-30) I had strained my wrist during a snowboarding holiday, and then aggravated it more by falling off my bike a couple of weeks later. My wrist was in pain what ever I did, and working out with weights became a no no. The powerball has allowed me to reduce my recovery time and improved my wrist strength compared to prior to the initial strain.

#Great product and great fun (2009-05-25) I wasn t sure exactly what to expect. What arrived was a solid feeling product looking a bit like one of those 20 Questions balls but much heavier. Giving it a quick pull with the string produced an interesting sensation of movement inside the ball but it took a couple of attempts before I got the hang of making it speed up. Once you get the idea it s exhilarating and much more work than you would imagine.

#Great product - great service (2009-05-25) Absolutely love it! No problems. I m getting better by the day!Comes with 2 strings, after a few days I learned how to start without the string.

#POWERBALL WOW!!!!! (2009-05-06) It takes you a little practice to use this thing, but once you can use it properly this is an amazingly effective exercise device. It works by having a spinning mass inside, which you can accelerate by fighting its angular precession by rotating your wrist. The faster you spin the mass and the tighter the circles you make, the more force you have to apply. What s great about powerball is that it is so small, so simple, and yet it is effectively an entire weight set. Even better, it works out all the little tiny fine tuning muscles in your arms that yo...
