Love this as a part of my daily cleaning ritual! The smell helps knock out anything that might not smell right. Plus I know it does a great job. I newly found this and now always have at least a bottle for cleaning.
I tried to only breast feed my daughter, but was unable to do so. We tried other bottles for her once we switched her to formula, but she always spit up/threw up. Once we found these bottles she almost never spit up/threw up again. These honestly make a huge difference in the fact they do not hold air in one spot. I recommended these to anyone I meet!
