The wrist ball is mainly composed of three parts, the inner precision rotating sphere, the outer transparent hard plastic shell, and a fixed rubber ring on the outer shell; the sphere shell has a round opening on one side, and the wrist ball can be operated through the opening. Through the opening, you can also see the two outermost rubber bands of the inner sphere, and there are arrow marks on them. Through the corresponding arrow direction, our fingers can move the inner sphere; the outermost rubber ring is detachable, this one The rubber ring is not only convenient for us to grasp the sphere, but also can increase the frictional resistance after the wrist ball starts to rotate. It should be known that the centrifugal force generated by the wrist ball is very large. If you are not careful, you may throw the ball out.
I am a 70-year-old woman with a retired medical doctor and have been in medical work for more than 40 years. I recently underwent surgery for carpal tunnel syndrome and cubital tunnel syndrome (8 weeks ago), and my hands are very fragile. I am using NSD Power to automatically start the spinner to repair the injured arm/hand. I received my device today, and although my condition is very weak, there is no difficulty in starting it. Any negative comments seem to be for the inability to start this device. If I can start this device, anyone can. The secret is to resist the force exerted by the spinner. Due to my weakness, I have to move my hands and arms very slowly, but my arm movement will be affected by the resistance provided by the spinner. I have another device that cannot start with a string or any other way because it does not have an automatic launcher. I gave it to my son. If you don't try to force the use of this auto-start spinner, it is easy to use. Those who designed this should be applauded. Anyone who is unable to start and use this device does not have enough patience. It works, and it works very well. Thanks for the auto-start spinner. I am very happy about it.

Absolutely worship! I used to sell something in a novelty store a few years ago. I haven't seen it in years. When my artist daughter started complaining about her wrist pain, I knew she needed one of them. This is when I remember. Good balance and endurance are good, not a real deal. Our doctor is very happy that she found the right way to increase the strength of the wrist. Fully recommended for people with wrist pain
