I have been dealing with Carpal Tunnel Syndrome for many years. I am primarily bothered at night, being awakened by pain and numbness. Wearing a brace to bed addresses the problem but is just trading one discomfort for another. I have been using this gizmo for a few weeks now and have noticed that I am not being awakened as often at night. It took some practice to get the hang of it and I still have trouble getting it started reliably with my non-dominant hand, but, once mastered is easy to use. Update: I have now been using this spinner twice a day for over a year. Although I still occasionally notice a bit of numbness in my hands when I get up in the morning, the Carpal Tunnel Syndrome improvement has been remarkable. I no longer need to ever wear braces to bed and am seldom awakened by pain and numbness. I can now "start" the ball reliably every single time with each of my hands. I don't have any numbers to prove that my grip strength has improved since using this spinner, but, I seem to be dropping things less often. Update 2: It has been almost exactly three years since I began using this spinner twice a day. Although I still have some Carpal Tunnel Syndrome issues, they continue to be trivial. Alas, this spinner appears to have lived its life. The rubber ring around the spinner that makes it easy to grip was beginning to stretch and slide about. I was also having trouble starting the spinner. Eventually I heard something crack when trying to wind the spinner up. After that, the thing was very much broken. After three years of daily use, it was time for a new spinner. My new spinner is just as awesome as my original. One improvement that has been made is that the arrows indicating which direction to rotate the ball in order to wind the spinner up are MUCH easier to see on the new spinner. A great product made even better with just one tiny change.

I bought two of the cheap 15 dollar spinners and they are absolute junk. Sent both back. Could not get one of them to consistently work. You get what you pay for. This unit works flawlessly and easy to keep spinning. Do yourself a favor buy this first and skip the cheap spinners that are not worth receiving even if they were free.

This auto start NSD spinner gyro ball is excellent. It helps my wrist pain. It may not work for everyone but in my opinion if you’re going to buy one of these I highly recommend this one. It seems to be made very well. I paid for this, it wasn’t sent to me free to review. I did try a cheaper one at first, and it worked poorly.

This is kind of a weird piece of exercising equipment, but I've found it useful and fun. I got it to help avoid additional tendonitis in my elbow due to archery. It seems to have done that, although giving the affected elbow some rest first also helped. No substitute for that. I have had no problems since I started using this regularly, however. I'm not convinced of its central role in that, but I do seem to have stronger support muscles all the way up to the shoulders as a result of using it. And because it's fun to use, I'll keep using it. I don't recommend using it if you are already having some pain. Rest the affected part and then start using this as a preventive measure, and keep using it. I usually do a minute in each hand, two times through, per day. At first it was hard to get going, but now that I've got the hang of it, it's pretty easy to get it spun up. I do better with my right hand- my left hand isn't as coordinated and I can't do the finely tuned rotation as well. However, I actually spin it faster with my left hand once I get it going, though I can't keep it going as long. The thumb wind-up start on this model is worth paying extra for. I wouldn't want to have to use a string to start it each time. It takes a while to spin down, so you can switch hands and get it spun up to speed again without having to restart it. The rubber band around the middle gets a bit out of position sometimes, so I flipped it upside down and leave a little gap so it rests on a ridge and it stays in place. Makes kind of a neat whirring sound when it's spinning fast. I wouldn't waste money on an RPM indicator- I'm not sure why you'd care. ***April 2019 update: The ball stopped getting into high gear, so I took it apart and cleaned it (Three tiny screws; do NOT lube it with anything!). It worked for another month but now I can't get it to really spin up, so I'm ordering another one. 4.5 years isn't a bad product lifetime for something like this these days. By the way, it still spins, but doesn't go into that whirring, high resistance mode where it starts sounding like a prop engine plane when you get the gyro really going, and eventually it just slows and stops. Some people that complain it doesn't work may not be getting it to that resistance point- takes some practice- or they may have gotten a defective unit. You will definitely hear and feel the difference from the spinning when you first start it to getting it into that resistance mode.

For all the reviews that state something along the line of "quickly spins down" or similar, you simply need to get the motion of your wrist correct. As stated in the instructions (and various videos), once the spinner is moving you need to use a steady "stirring" motion with your hand/wrist to get the gyro to keep spinning. It only took me a couple of tries to get this working - but others may need a bit of practice. Note that the starter is just that. It will get the spinner moving fast enough to start, but nowhere near fast enough to offer much resistance. Once you get the RPMs up, the resistance you feel increases quickly. I got the auto-start model and wind it with my thumbs. For those that don't have the hand strength to do so you may find that pulling the wheel across a countertop is an easier way to wind it. Because the torque push back you feel in your hand is directly related to the speed the spinner is moving, you are in complete control of how hard of workout your hands / wrists / forearms get. If you keep the speed fairly slow, it will be a very easy exercise. If you make the spinner go very quickly, you will be giving your hand a very firm workout. I purchased this to help rehabilitate my hand after breaking it. I'd lost nearly all my grip strength after having a cast on for about 7 weeks. This has helped a great deal and I find it much more fun to use than some of the other tools I've also been using like rehab putty and grip springs.

Originally purchased for my teenaged baseball player for grip strengthening (batting). Pros: Reasonably priced Cons: Broke in under a month under normal use Bottom line: Junk and possibly harmful for elbows of teenaged pitchers. The manufacturer pitches this product as great for conditioning the forearm for tennis, batting, golf - any sport that involves gripping a shaft. I purchased this product with that in mind without first doing some research and obtaining expert opinions from sports medicine. I know better and did not do this. In talking with several orthopedic surgeons and a physical therapist, they cautioned use for developing teenaged elbows, especially those who pitch baseball. There is virtually no scientific literature on the pediatric effects of this device. Its breaking was actually a good thing! I elected to be conservative and not replace the device. Instead, my son uses the FlexBar manufactured by TheraBand to strength the forearm and stabilizes the elbow.

I open the box with a measure of doubt, seeing the price—more than twice the humble plastic-rotor gyro ball I recently owned— and I think to myself: is this extravagance, or improvement? I spin it up. O quiet revolution! No shrill plastic whine filling the room, no drowning of the evening news or the chatter of the television. Instead a steady, confident hum— I work the wrist and forearm while the voices from the TV carry on undisturbed before me. I note also the self-start, that small but noble convenience— as quick and faithful as the plastic model I used before, no fuss, no struggle, only a smooth awakening of motion. And as the rotor gathers speed, my doubts of the purchase flee— as if flung away by the quickly ramping RPM. Yes, it costs more— but the quiet, the smoothness, the simple pleasure of using it make the judgment clear. Should I need another gyro ball in the future, I would not hesitate— I would choose this one again.

Years ago I owed one of the plastic blue ones with the green ball. It was practical but the bearings began to go after a while. Now, years later I purchased this one and I'm well impressed. Reading the description, I did not fully realize the inner workings were all medal parts supporting the gyro ball. It does not require a pull cord to kick it off and is crafted with a spring mechanism that allows you to get it going effortlessly. It is a nice desk stress reliever and good forearm developer to boot. It is highly recommended and worth the extra change.
