Watch a video, great buy

So I have really weak wrist and I thought this would be great for exercising them. Turns out it is. But watching a few YouTube videos were very helpful. Once I got the ball going and I understood that I should only be moving my wrist it became a bit easier. And it lit up. It is a basic model. A great place to start to see if you like it. 
it's made with a hard plastic casing on the outside. It comes with 3 bands black, red, and blue. The inside made of metal and rubber. It seems well made but I would be careful not to drop it.
