I don't have the spinner, but I have the cube. I bought it to help curb my anxiety attacks that I sometimes suffer from. Overall, I do feel like it distracts me enough to forget about the anxiety, thus preventing an attack from happening. I know a lot of people have kids who use these for either autism/ADD/ADHD/anxiety, and it bothers me that this has become a "fad" recently because I feel like these items should be reserved for those who need them. It's not "cool" to need a device to help you focus or calm yourself down. Trust me, I would rather NOT need the fidget cube and be anxiety-free than look "cool" by playing with one. And I'm sure plenty of autistic/ADD/ADHD/anxiety kids would rather not have their problems either. If my kid asked for this, and didn't have a real need for it, I would not buy it for them. I think it's a great thing for those who truly need it, but for those who don't, I find it offensive.
