Perfect!
These fit perfect and totally fixed the low output issue I was having! My other valves were getting a little loose after a short period of use but I was using it often. I thought it was me but it was just the duckbills thank goodness! Reasonably priced and easy to replace on my pump.

Great Quality
I bought these as a cheaper alternative to name brand for my pumps and they were great. I can’t find any difference in quality. 10/10 from a pumping mom.

replacement duck bills
I'm order to keep your breastpump effective you should change parts every so often. The duck bills especially wear out. These are great replacements, they fit and work as they should.

DOES NOT FIT M5
Not compatible with momcozy M5 despite saying this in the description. Don’t waste your money.
