The NSD Powerball is a hand gyroscope - a tennis ball sized sphere containing a computer balanced flywheel which can revolve freely inside.
As soon as you put the flywheel spinning (by means of subtly rotating your wrist), it begins to generate an extraordinary force (otherwise known as gyroscopic inertia) which acts immediately against your fingers, hand, wrist, arm shoulder and even chest!
The ball weighs less than 300g but can pack a 40lb punch depending on the speed at which the rotor is spinning -the present world record is over 16,000rpm!...can you even come close?? :-)and will make even the fittest and strongest people on the planet burn because it is hitting muscles in the fingers, hands, arms, shoulders and chest that you simply won't have used before with conventional forms of exercise.
How does it work?
Definition: NSD Powerball is a finely engineered and precision crafted gyro consisting of a rapidly spinning rotor enclosed in a solid [hand held] outer sphere.
You set this rotor in motion using a cord or your finger and build its speed by subtle rotation of the wrist. It contains no motor or no batteries. All of the energy which we describe below comes from you dear reader and the stronger you are, the faster you will be able to make your NSD Powerball spin!
(Do you think you've got what it takes to break the current world NSD Powerball spin record?)
...and the faster you spin the inner rotor the more inertia it generates and the more resistance it subsequently inflicts upon the fingers, hands, wrists, arms and shoulders.
Unique workouts...
These unique instruments generate massive force and put the shoulders, arms and wrists of the user under big pressure - making them ideal for fitness enthusiasts and virtually every kind of sport imaginable.
And in addition, because the inertia (or gyroscope resistance) generated within the NSD Powerball is directly proportional to the speed at which you are spinning the rotor - these precision instruments are just as capable of gently rehabilitating a damaged limb (wrist breakage, carpal tunnel syndrome, RSI, tendonitis, tennis elbow, golf elbow etc.) as they are at building huge muscle in the arms and shoulders - its a completely non impact form of exercise and is all about rotor speed.
But it's not all pain!
Most NSD Powerball models (excluding classic edition) have a built in digital speed meter which measures the number of revolutions per minute made during each spin.
This translates into a whole pile of fun if you happen to plant one down in front of a group of guys or girls, each of which will be magnetically drawn to bettering their own last score, or that of their friends, even when they feel their arm is about to fall off! (which it will after about 10 seconds of maximum speed).
Just how fast can you spin it?
Of course, all that wrist & arm building will come in handy..
..whether you play golf or tennis (or any of 1000 other sports!), ride motor bikes or mountain bikes, play the piano or drums, it doesn't matter - NSD Powerball will put so much power into your fingers, wrists, hands, arms and shoulders that we absolutely guarantee you'll see a dramatic improvement in all sports & leisure activities you perform each day, regardless of what they might be!
250Hz range has been certified to 15,000rpm but will clock well in excess of 16k if you can do it!
Simply just pull back the rotor and spin! No strings, no thumb start, no flick start... just wind it back and let go for a perfect start every time!
Comes complete with a digital speed meter (batteries already installed - approx 3 year life span) to allow you monitor your power improvements on a daily basis and test your skills against both your friends and Powerballers
Powerball will repair or replace a Powerball which is send to them (buyer to bear return shipping to powerball). However most often Powerball will send the replacement parts and manual on how to replace the part FOC, just fill in the details & state the problem here www.powerballs.com/repairs
