"This item is so high quality and durable. I should know, as I've used it for hours a day, every day, since I got it. I bought one for my friend who has ADHD at the same time, and they really like it too. They'd wanted a stim toy that's relatively small and quiet to keep in a pocket, and this fits the bill. I'll surely buy more."
