I SWORE I wasn't going to ever buy one of these but I'm really glad now that I did. This is a really cook gadget to have around. I've used it do far to twiddle and "figet" with while writing, working on the computer, and reading. I never really thought much about how often I fiddle around with my hands while I'm trying to concentrate. This is easy to hold and use. It feels really neat when you spin it and then turn it side to side. My children actually do weird tricks with it, which I have yet to master LOL. I really like it and I'm gald I got one now. It actually seems to help me concentrate better.
