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

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

So I came across this spinner while researching about carpal tunnel cures and exercises. This popped up in one of my searches and looked it up on Youtube. I was skeptical at first and I know I've only had it for a week, but I can tell right away that it somewhat energized my forearms and wrist. Best to watch the instructional videos in the internet so you can learn the different techniques. I have to say that this is worth the money. I've actually recommended this to some of my co workers who have carpal tunnel.

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.
