Manufacturer's Description

Powerball is a dynamic and completely revolutionary new gyroscope that literally explodes with mind-numbing torque and inertia once you activate its internal rotor.
EXERCISE • PLAY • COMPETE
Ideal for sports like Golf, Tennis, Squash and all other activities demanding power in the arms, hands and wrists. Great for musicians too! Drummers, guitarists, pianists (in fact most musicians!) will benefit from the increased strength and dexterity that an NSD Powerball will give them!
How It Works
Merely the size of a tennis ball and weighing about 250g, it looks harmless enough, yet this unique gyro can spin at an incredible 15,000rpm and generate over 40lbs of force - all of which is applied to the fingers, hands, wrists and arms of the user. No matter how fit or strong you already are, using the ball for just 5-10 minutes each day will unconditionally guarantee a substantial strength increase in the full muscle groups of the lower arm and wrist, within a very short time frame.
The Fun Side
The onboard computer/rev. counter makes Powerball one of the most seriously addictive products since the Rubik Cube! Place Powerball on a table in front of a group of guys and sit back to watch what happens; Round and round it will be passed with each player trying their hardest to beat the high score that someone in the group will inevitably get!
The Gentle Side
As a ‘non impact’ strengthening device, which exercises every muscle group in the forearm, Powerball has been medically recommended as an ideal instrument by which to rehabilitate an injury to the hand, wrist, forearm or elbow. It works isometrically to gently stress the damaged area in a perfectly smooth, even manner which cannot be replicated by normal exercise, therefore lending itself to the gentle rehabilitation of Repetitive Stress injuries, Carpal Tunnel symptoms and Arthritic conditions.

Powerball - Fantastic! Buy one now!!,
By The Admiral (UK) - See all my reviews
This review is from: Powerball 250 Hz Pro (Sports)
I wasn't quite sure what this was or exactly what it did when I saw it. However I ordered it after reading a few reviews. Stupid thing to do? Absolutly NOT! Powerballs are brilliant, but hard work. It looks like a plastic ball encased by another plastic ball. But set it going and its more of a work-out than using free weights. Once you set it going give it five minutes, if that!, and you will feel it working. It works out your fingers, wrist, forearm and upper arm. For somehing that looks so simple it is absolutly amazing.
After I brought one I showed a few mates, every person I showed now has one. Most reviews seem a bit extreme, but they really are as good as these people say. Worth the next-to-nothing price they are. Buy one and you won't regret it!

Very Addictive,
By
This review is from: Powerball 250 Hz Pro (Toy)
I've been using powerballs since the start of the year and the difference it's made to my arms is definitively note-worthy. They are a little hard to comprehend at first since the way people explain their use can be a little confusing. They work purely on moving your wrist and arm in an egg whisking motion. When you pull the cord, the internal ball starts spinning, when you move your wrist, the ball will resist by means of inertia. My advice would be to `feel' the resistance and push against it, this in turn pushes the ball round, the harder and faster you push, the greater the resistance and the faster the ball spins. There are no motors or gears or anything like that, just a gyro in a shell. It took me about 2 hours to figure out how to keep the ball going, but once you catch on it's extremely addictive. One warning, you will get blisters, but probably worse still, you won't be able to put it down even if you have them, it's that addictive.
My advice would be to give them a chance if you can't get it straight away, try holding it in a different way, take it slow and whisk wide. Also, and more importantly, get the balls with the counters, these are what make them addictive, just getting those few extra rpm's is what makes this fun, not to mention keeps competition going with friends. Do not be put off by your low speeds to begin with, most people start at about 7000 - 9000 rpm and then level off at 12,000 rpm, it's at this point that things get tough since the resistance goes up exponentially. 12,000 rpm is actually not a bad score, although the leader board is filled with scores of 13,000+. At 14,000+ the entrants become a bit scarcer, and at 15,000, there are 14 people at last check, but the mighty Akis is some 500-rpm faster than the next best at 16,317. Also, don't cheat and use oil, D40 or other lubricants, this will in fact make things very difficult since the ball won't get any grip and will just spin on the spot, that's even if you can get it started and cleaning them can be a pain. Speaking of cleaning, yes, like the old joke about cleaning your mouse ball, so too must you clean your powerball which can be a little tricky, go to the official website, they give details on how to open it up (some a little more extreme than others) and use something like methylated or surgical spirits with a non lint cloth, DO NOT USE white spirits. The warranty that comes with them is exceptional, for the most part they will replace broken starter strings, but you won't need them once you can flick start. They will also replace the washers and the plastic sleeve free of charge, yet some have managed to get the rotor replaced if it breaks (rotor breaks are very rare). In all, an amazing product and highly recommended.

The best choice of Powerball to go for: 250Hz Pro,
By
This review is from: Powerball 250 Hz Pro (Toy)
There are a lot of Powerballs to choose from; if you're undecided then go for this one. It has the digital display which is a must-have, and none of the other gimmicks the other Powerballs have that only serve to slow the ball down.
Starting the ball can be awkward with the lace, but after a while you will be able to do this with your hand and bin the lace - at this point the Powerball is a lot more fun and accessible. It will take a few days to learn the proper technique of spinning the ball - persevere at this because once it is mastered you hardly have to move your arm to keep it spinning. It's surprising how much forearm muscle you'll use with this minimal movement. They are a lot of fun and are one of the best ways to build up forearm strength. A bit like the hand spring grips you can get but you are more likely to use the Powerball because of the variety of things you can do, and the fact there is the challenge of beating your personal best. Highly recommended, and a great gift idea. 2115|RFPO569LNKJ7J;2115|RRNIPDINUI2XP;2115|RYZS7JZ0250OI;
