I bought this one for myself to keep me busy while watching tv. And i can say that it really does help me out alot to stay focus. I love the fidget spinner! They are very smooth compared to others one I have. They dont make any noise at all. Some spinners are annoying like that. You cant pull the caps off this one which makes me happy not to worry about choking. Love this fidget spinner and i definitely will be buying more for Christmas though.
