I actually got this because I have an autistic child that can't sit still, or kep their attention on anything for long. I needed something that wouldn't freak them out and yet would help them to adjust their attention accordingly! This does the trick. It is just enough to keep them trying over and over to make shapes and changes to it, that they are very quiet during important events. Even if you don't have a child with autism, this is a good thing to give someone to play with. Makes a very nice gift! This is well made and should hold together well.
