8pcs Duckbill Valves Compatible with Momcozy M5, Replacement Duckbill Pump Parts Accessories for M5 / V1/ V2 Pumps, Made by Tbuymax

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.

These are exactly what I needed, I feel as they provide better suction too!

Great to have multiple replacements of these. They fit my MomCozy M5 and V1 Pro cups

Great replacement for the price. I like to replace my parts pretty regularly

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.

Perfect replacement parts for daily breast pumping use.

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.

These work great with my pump! They fit perfectly.

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