Click & Drink 360 Stainless Steel Learning Cup

I bought this as an alternative for the munchkin plastic 360 cup but this one is not the same, this one is only leak/spill proof when you push the middle of the lid down which stops them from being able to drink out of it altogether therefore they cant walk around with it or use it on their own without watching them like a hawk which defeats the purpose of buying something like this for a toddler.
