Negative Positive
Title: Not good at all
Review: I do not recommend this bottle. First of all, the extra parts make it very unhygenic when making milk, especially when you are outside. It doesn't reduce gas as it claims to be. Even though it came with a small brush, there are still areas you cannot reach to clean. And worst of all, even with the stopper, this bottle leak if it is not upright.
