Manufacturer's Description

Powerball is the world's most powerful hand gyroscope, generating speeds of over 16,000 rpm! Simply by starting up the Powerball in your hand and rotating your wrist faster you can develop incredible speeds and increase your strength. Powerball is seriously addictive for all ages, making it ideal for play, exercise, or fun competitions.

Powerball is a dynamic and completely revolutionary new gyroscope that literally explodes with mind-numbing torque and inertia once you activate its internal rotor. It's about the same size as a tennis ball and weighs just a little more, but take a Powerball in your hand, set that rotor in motion with the cord provided (or use your finger when you get used to it) and you'll experience an extraordinary sensation. Powerball slowly comes alive with gyroscopic force - a sublime yet pleasant resistance to your movement which is transmitted directly into your wrist and arms and which provides soothing, non impact rehabilitation at these lower speeds.

Bring your new Powerball up to 10,000rpm, the forces are now much stronger, much more vibrant. Higher! Take it right up to an unbelievable 15,000rpm at which point it's exerting almost 40lbs of pressure on your limbs and is travelling at nearly 250 revolutions per second. No batteries, no motor, just pure gyroscopic power

Not suitable for Children Under 14yrs

Customer Reviews

Powerball is great!
I bought a powerball purely out of curiosity and I'm glad I did. It's great fun and worth it's money. I would only suggest to anyone not to buy this model as it doesn't have a timer so you can't see how many rev's you're doing. It's better to pay a bit more and get an electronic one with flashing lights too.

Powerball Screamer
This screamer version is based on the original powerball but with an added twist and it is just as fun as the various other models. I have been using various powerball for over two years now and I love it as much now as when I first got it. The manufacturer's description really doesn't do this product justice, although their website does. If you use this powerball at low speeds it is great for RSI and other wrist/arm injuries. At high speeds it gives an amazing workout and really builds up all the arm and shoulder muscles. The build quality is incredible (do not be tempted by inferior wannabes) and the lifetime guarantee is unbeatable. I've had to replace a small part already (due to my intensive usage!) and they sent out the part quickly, free of charge and with full fitting instructions, can't say fairer than that! The screamer is a fun variation to the original powerball and a great addition to the powerball collection. It is truly addictive and put it on a table in a room full of friends and you will all soon be fighting to out do one another. I could write so much more about this product, but really you've got to buy one and try for yourself, you will not regret it!

Great for guitar heroes
My son plays death metal guitar for about 6 hours a day! This has strengthened his hands. I wish he would play Neil Young, David Gilmore or Simon and Garfunkel. I wonder if there's a device to get him to do that?
