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.
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.

-self love...way to dangerous

Get this if you are not a girly man, or if you are a girly man but do not want to be anymore . NO MAS!!!!! If you are looking for huge muscles, go to the gym. If you want huge fore arms, go to the gym. But if you want to get better grip, go to the gym. Also use this contraption. It really does work on grip and is easy to use. i work with a couple people in my office and we usually just pass it around during the day. Every co worker that has used it has mentioned their grip strength increasing...except for Dave, everything is dificult for Dave.
