My kids and the neighbor kids will literally spend all afternoon laying them all out and trading them. Let me say they are not fighting over them, so that has not been a problem. I personally think they are pretty cute...bright colors and endless shapes... they are sort of/in a way little tiny pieces of (plastic) art. Anyway, I can see why they are such a hit.
I also know many of our local schools have banned them because of the distractions. My kids beg for more every day, although I have stuck to my original plan of only buying each child one pack. This is the biggest fad I have seen in a long time!
What do you think of them?
