“Nice idea but not practical. The lid comes off easily and the contents are spilled. I will use it as an (overpriced) open cup. It could have been great but it is not unfortunately. Not for us at least.”
“I don’t know how I feel about this cup. First time my daughter used it she managed to squeeze it enough for the kid to just pop off and milk went everywhere. You don’t have to squeeze too hard for the lid to pop off so I can’t say I’m very happy with it unfortunately.”
