Great replacement parts
For those that do not know, the Doc Browns Anti-Cholic bottles are great bottles that work as advertised, particularly in their anti-cholic function. This stem is the feature that permits that function. The bottles also travel well...which is how we kept loosing these stems and stem caps. So I bought a few more. Bein as how these are the exact same brand and part they function in the bottle well. I just wish that Doc Brown would amend their bottle brush design to include a brush that would effectively clean this part. But I've never had one break, the part itself is great, and the bottle design as a whole fulfills its promises.

They may be annoying to clean but the flow is so much better with them in the bottles. I like to have extras of these and exchange old parts for new ones

Great Product
I love Dr Brown bottles! My little has used them since birth. I ordered these extra ones as my MIL ordered bottles that do not have these. I like to ensure I use them because they truly do help avoid air bubbles and air intake.

Bottle Part Replacements
These are great parts to buy if you want to convert the glass, narrow even flow bottles to anticolic like Dr. Brown. These parts are easy to clean with the right brushes and are durable making them a good value. I personally have not had an issue with leakage and the flow is appropriate for my baby.

After a few of these went missing I was happy I found a seller who sells replacement pieces. Came as expected. Thanks!

Il faut commander les nouvelles tetines Dr.Browns , les anciens modèle n'est pas compatible... les fillets ne sont pas assez long.

Todo perfecto, embala perfecto a las otras mamilas de Mr brown que ya teníamos, me encantaría que fuera un color más discreto o bueno, ya sea azul o rosa como las mamilas que venden pero es un detalle meramente estético; Es funcional, que es lo que importa. Muy contentos con la compra
