Great starter cups.
We tried several cups when transitioning our son from a bottke to a sippy. These are the only ones he took to that weren't straw cups. He didn't like any of the cups with hard spouts. We use them much less frequently now though because they don't hold up well to his chewing (no soft spouted/strawed cups really do). They were great while we were able to use them though. I love how easy they are to clean.
