The ultimate in engineering design, the Powerball offers the same user-friendly features as the DynaFlex Pro Plus, but incorporates an onboard generator and balanced rotor. By activating the gyro, a dynamism (motion) is created, which will activate blue LED lights that are located in the interior of the gyro. The faster the unit runs, the brighter the lights will radiate until the whole hand is engulfed in a bright glow. More importantly, the Powerball generates 40 pounds of torque and speeds of up to 18,000 rpm, making it an ideal tool for physical therapists, trainers, and athletes who want to improve muscle condition and/or rehabilitate nagging upper body injuries.
As a bonus, the removable end cap lets you attach an optional speed meter, making it easy to monitor your exercise time, rpm speeds, and other functions. The PowerDock docking station, meanwhile, both activates your Powerball gyro and serves as a fantastic and modern-looking base to rest your gyro while not in use. Just hold the button for a few seconds and hold on tight. The docking station requires two AA batteries (not included).

 Powerball Great, Base WorthlessJan 09, 2009
I purchased the Powerball and docking station because I knew my son would have a tough time starting it using only the string. The dock ended up being worthless. The starting wheel wobbled and didn't appear to have enough power to start the Powerball properly. I emailed the manufacturer but was given the brush off basically telling me if you don't like the way it works, send it back.

 Easy to use out of the box - never used one before - learn the "trick"Dec 02, 2008
After reading some of these reviews, I was worried. I inserted the batteries, inserted the powerball into the docking station and held it down while pressing the button. It barely spun as it started turning sideways. I was thinking the negative reviews were correct or mine was broken. Then, I noticed the picture showed it not being held down when in the dock. So, I aligned it, let go of it, and pressed the button. It immediately spun up to a high speed and I picked it up.
The 1st time I tried it, it slowed down. Again, I was thinking the negative reviews were correct. But, I went to their site and watched their video. Once I realized that the written instructions (which say left to right motion) are wrong, it was easy. You rotate your wrist in a simple circle (like you are drawing a small circle with a pen). When you do this and it is spinning fast enough, you suddenly feel it "catch" and start speeding up. If you circle too fast or to slow you can feel the change in resistance and stops increasing the speed. So, by circling at the speed that gives a constant pressure back, it gets faster and faster (you can hear it revving up). I found that I could learn the motion with bigger circles, but the big speed up happens with smaller circles.
I then tried the string start and it works, but you have to pull really fast. Pulling hard is useless, pulling fast is what is needed (it has no real resistance).
I have not tried a thumb start, but I can see how it would work - you need to have the circling motion just right though (cannot take long to catch the right speed).
I have only had one day, so cannot comment on how well it helps my wrist pain (computer use). But, it does feel like it will strengthen my wrist, which is what I need.

Great forearm strengthening Aug 18, 2008
This provides a great forearm and wrist strenthening exercise perfect for tennis or overall strength, especially if you have tennis elbow and weak wrists.

 It doesn't workMay 25, 2008
When I bought I thought I could avoid start power ball manually. Forget this, because it's week and simply doesn't work as purposed.

Great for arm strength and conditioning.May 23, 2008
This item is perfect for me for two reasons:
1) I type very fast and use the computer very often.
2) I'm a tennis player.
I purchased this in September of '07 and have been using it ever since, almost everyday. I bought this with the intent of helping me achieve better arm strength and grip since I play tennis. I have not had tennis elbow or any pain or soreness in my hand,wrist,forearm,etc.
If you do not use proper technique with the string, the tip of the string can easily break off and then you'd have to use the dock or the advanced techniques. The dock is constructed very cheaply IMO. Looks like something someone made in the garage. It is effective though, and the only complaint I have about the dock is that I have to keep buying batteries (so I'd recommend rechargeable batteries, it uses two-AAA).
Don't read some of these reviews on here that say the dock takes forever to start up the ball. It only takes maybe 5-7 seconds to get the ball started up using the dock, which isn't that bad considering it already has a ton of momentum for you to work with.
Also, this isn't just a "toy" like some of the reviewers here have stated. If used properly with the right technique and repetition, you'll be using this thing everyday. I'd definitely recommend it for those who need physical therapy, those who play tennis a lot, and those who use the computer as often as I do.
All in all, I don't have any real complaints about it. I bought my Gyroball from Sharper Image and purchased an extended warranty on it. Don't know if Amazon offers one on their website though. The only reason I gave it 5* despite the criticisms about the dock and string are for the performance and usage of the gyroball itself.
