I bought these sippy cups for my daughter after some unhappy encounters with a few other brands and I haven't looked back since. These are the sippy cups that helped us get her completely off the bottle and she loves them too! They never spill and they are easy to drink out of (toddler doesn't have to try to hard to get a drink). They only thing is they are not that hard to open so if your toddler gets smart like mine did they might get them open! But that only happened once :P
