My toddler loves this sippy cup - colors are vibrant, comfortable to use and it DOESN'T LEAK. I also love the attached cover - no dropped or misplaced covers. in fact, my toddler now closes it back up herself when she is done with drinking. it's a HUGE improvement over Oxo's prior version of the cup, which we also own. My only complaint is that Oxo doesn't sell replacement parts. Inevitably the spout will wear, and you will have to buy the entire cup all over again rather than just buying a replacement.
