JIN BD Auto-Start Wrist Trainer Ball - Gyroscopic Forearm Exerciser for Strengthening Arms, Fingers, Wrist Bones and Muscles

Good for strength building, durable and value

I got this to help with my sore wrist since I am on the computer all the time. It takes a little time to get used to. At first, it wasn't lighting up, but I later learned it was because I wasn't moving my wrist in the right way to maintain the momentum. It needs the right kind of wrist action to keep the gyroscope moving and light the lights. I did a quick search on YouTube.com and found great instructions on how to use it. This is a great workout for the wrist, and it helps me overcome overuse from typing or using my mouse. It's also a lot of fun in general! Never hurts to have fun when you're exercising!
