6PCS Duckbill Valves Compatible with Momcozy M5/M6 Wearable Breast Pump, Replacement Pump Parts Accessories Compatible for V2 Pro/V1 Pro Hands Free Breast Pump Parts, Not Original Mom Cozy Accessories

I bought these because I was concerned I was having less output using my Momcozy M5’s with a longer flange. These fit my M5’s perfectly, are easy to get in and out of the pump flange, and provide good output. They’re very comfortable to use. Definitely would purchase again, especially for such a good price.

These replacement parts fit my momcozy m5 perfectly! I was a little skeptical because most duckbills are loose but these are better than the ones they send with the pumps. Will repurchase again once these are worn.

These fit great, and as an added bonus, they fit in my spectra as well. I no longer hate pumping as much as I used to!

Fit my MomCozy M5 breast pump perfectly. Highly recommend for the great price and quality of the product.

Works great in my momcozy pumps

Works well with the MomCozy M5 pump. It’s not as snug as the original cups.

Unusable - the flange arrived defective, the hard plastic is bubbled and cannot connect to the milk collection cups. In process for a return but in the meantime without a flange. Would not purchase again from this seller. UPDATE Replacement received for return and has the SAME DEFECT. DO NOT ORDER!!!!! Waste of money and time.

Fits great. Definitely helped improved suction.
