NSD Manual Thumb Wind Start Spinner Gyro Ball – Up to 15,000-18,000 RPM Premium & Durable Hand Strengthener and Wrist Exerciser for Grip Strength Training, Forearm Workout, and Pain Relief

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.

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.

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.

Love it. Broke arm just below wrist. 10 weeks in splint. Cast and brace. Lost strength and mobility. This is helping.

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.

Returned it. Tried repeatedly to get the spinner to work but failed. I'm only willing to go so far to "master" a piece of exercise gear. Good luck to those who solved the technique.

Works great, I have one for me and one for my child!

Works well easy to use

Works well, excellent for strengthening grip, wrists and forearms.

I have had numerous power balls in the past, and I think this one is my favorite. This ball has an auto start feature, which is convenient, but it lacks the colored led lights and and the electronics display at the top. As far as I’m concerned, the electronics are not necessary or desired because the addition of the electronic disc at the top of the ball hurts the palm of your hand and your hand covers the display most of the time. The colored lights are fun at first, but not necessary to the task of building hand and forearm strength. This ball runs quiet with no real vibration and I can use it while watching TV with my wife without her giving me “The Eye” if you know what I mean! If you are new to having a powerball or an experienced powerball user this is a good choice and is all you will ever need.

so relaxig for hand muscles

I cannot get this item to work although I follow the instructions. It just stops spinning. Bitterly disappointed.

A superb product for strengthening the arm and wrist. Just a few minutes and your done. Also helps with carpal tunnel syndrome and tennis elbow. I find it useful for people suffering from Parkinson’s as it creates a counter nutation providing some relief from involuntary movements.
