Query: Great when watching TV

Product is pretty fun and easy to use, but it took me probably a day or two to really master the movements of the wrist/hand. It can lose it's novelty if overused, but if you pick it up from time to time, it's still fun. Only negative thing I have to say about this product is that it can get a little noisy.. I wanted to bring it to work, but it seemed a tad bit loud.
