These are stocking stuffers (if I can quit playing with them) for both kids and adults. GREAT desk toy. I'm not so sure that kids will find it quite as cool as adults will. Looking for a teenager toy? I'll bet you this will earn a grunt of approval.
IT IS CURIOUS AND FUN!

The product is really cool! I got one for myself and several for grandkids, kids and friends. All of them were amazed at how it won't spin in the clockwise mode. Our daughter (43 years old!) played with it for hours while we were talking!! The product was everything that was advertised!

It was smaller than I expected -- but to be fair, I didn't look closely at the description when I purchased. But it does work like promised, and my 6 year old who lives for spinning things loves it.
