Been looking for a fidget spinner for a while to help with my something shiny disease.When I received the spinner and opened it I could tell right away it was better then the store bought ones. The spinner is a heavy durable product. I do not have a long attention span therefore playing with this at work during training helped me a lot. Another great use I have for it is when I am sitting in rush hour traffic going no where it keeps me sane. Would definitely recommend this spinner to anyone who has problems with concentration.
