Query: Worst Bottle on the Market

I have triplet girls so I have become an expert on bottles we have at lease one of every kind on the market. I must say these are by far the worst bottles on the market. They leak at random and when they do they make a mess all over your baby or the diaper bag. They are expensive and there are many cheaper bottles on the market that are 100% better. Do not waste your money on this product
