We have tried other bottles from well-known companies as well as from the same company with the wide mouth, but none accepted like this one. It is a bit time-consuming to clean compared to other baby bottles, but if you soak it in warm soapy water after each feeding, it is a quick process. Tested with both formula and breast milk

It loses a little milk when mixing, but it's okay because we accepted it right away since we started with Dr. Brown's from the first day!!

I deduct one star only for the pink. Do not get it. Prefer the green. I have both the pink and the green and I use them simultaneously for a year now and for some reason the pink collects excessively more yellow residue in the valve, which is already difficult to clean. I don't know if the material, due to its color, has a different affinity than the construction, but the difference is significant.

Overall, the valve is worth it because we haven't had any colics even once. Of course, we are a very small sample, it could have been a coincidence.

It's worth it, but not the pink.
