They are very much a fad, but I can say they help with fidgeting! I myself always feel the need to be moving or keeping busy because I get bored easy. This simple spinner gives me something to do with my hands and actually kind of works. It is definitely come to be used as a "toy" by many smaller children and we all know that children feel left out if they don't have what all the other kids have. Bottom line it will die down, but will forever be helpful to fidgeters.
