My son has a learning disability and this sort of toy/aide is very helpful. He has serious issues with focusing and he enjoys watching the slow green go pass from one side to the other. It is amusing as well as helpful. The shipping was a killer (appx same as the product) but it did come right away and it was worth it.

I have one of these on my desk in my classroom and it is great for kids who are getting a little anxious. They can sit and watch it for a few minutes and are ready to rejoin the group. It is sort of like a lava lamp. It can also be used for describing activities...
