Product Description
Introducing Powerball - one of the most unique and dynamic products available on the web today - 8 world records and counting!Just like the 250Hz Clasic model, the 250Hz Classic 'S' or Screamer is supplied without a digital speed meter (this can be added later if required) and has the added bonus of a series of precision-drilled holes around the rotor surface to produce a satisfying whine even at lower speeds!Also included are full operating instructions, 2 starter cords and the unique lifetime warranty. Please note that the noise is not to everyone's taste!Explosive, dynamic, exciting Powerball! Powerball is a dynamic and completely revolutionary new gyroscope that literally explodes with mind numbing torque and inertia once you activate its internal rotor.Extreme Powerball!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:Power ball 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.You want more? Take it higher...much higher!Bring your new Powerball up...up to 10,000rpm...the forces are now much stronger, much more vibrant. Higher! Take it to 12,000rpm...no, higher still...take it right up, thrashing and jerking as your arm and wrist try to control and calm it down, faster and faster it spins until you have it 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

Could not get it to work effectively. Maybe it needs a special technique like a yo yo? Must confess I am not good with yo yos either. I did try a lot of times but it spins for a short while then stops.....oh dear!
 Powerball Screamer December 20, 2007

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!

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.
