I like these cups because they are very durable and they never leak. They are also very easy to wash. I like the smaller part in the middle because it helps little kids grip onto it with their little hands. However, the cups are quite big. My daughter never drinks that much at one time. She is two, so she can't clearly tell me for sure, but I don't think she likes the size very much. She usually refused to take this cup and then takes a smaller one when I offer it.
