First off let’s say I love the look of this bottle. But unfortunately I am disappointed in so many things. This bottle is not double walled like the rest of their bottles are, but costs like it is. It therefore does not keep it as cool as it should. The inner piece is great for washing as removal is easy. BUT this piece leaks all the time if it’s not in and if it is then the kid can’t get a decent swig of water so even my 2 yo gets tired of using it. The cute little cap keeps the spout clean and is anchored so that’s helpful. But mostly the spout is annoying to get anything out of or it leaks like crazy without the valve in it. Great looks and seems thought out but really need to alter the spout so he can use it bc it leaks or he can’t get any water out. Also side note if this is for tiny children why is it so fat they can’t hold it in their tiny hands? Maybe a handle or make it thin. It’s so thick it doesn’t fit in kids car seats cupholders, which also makes him upset. Sorry but it’s a miss for my toddler.
