I feel like this cup really helped my niece learn to drink out of an actual cup! Definitely no spilling even when she would drop it constantly at first.

This is a good cup that does not leak. It has cute colours and two soft handles.

My little boy loves to throw his cups around, so this cup has been put to the test on a daily basis. It does not burst open and it does not leak - ever! My baby also loves to gnaw on the rubber sipper part, and it all still looks brand new. These cups are a little more expensive, but they're worth the investment if you're on the go a lot, or if your kid just likes to throw things!
