Both of these cups are great! I would've thought the straw cup especially would leak but neither of them do!

When using the 360 lid it will splatter if thrown for example if your child throws it off high chair but aside from that cup works as intended.

Love this brand. The only sippy cup that I have found that does not leak. We'll buy more again. Highly recommend.

My 14 month old loves this cup! We were using the Munchkin 360, but this cup seems to be better quality and less leaky.

I love this cup for my daughter, we haven't used the open cup functionality just yet but the straw works great and it wide enough that she is able to drink smoothies from this cup

This sippy cup is the style that I was looking for.

Perfect for our toddler, fewer parts so it's easy to clean, compatible with the other Dr Brown sippy cups we have.

great bottle for toddlers

Great cup my grandson just turned 1 and he does wonderful with it.

I love this cup and how easy it is to clean. my only complaint would be the straw cup doesn't have handles on it which makes it hard for my daughter to hold it.
