Was a Perrin fit for my mom cozy m5 my cousin is pregnant and put the Mom cozy m five on her registry and I recommended these for her and will be buying them for her again

Pensé que no le quedarían. Mi extractor decent go de horigen pero le quedaron perfectas

These were not compatible with my pump.

This replacement valve was a life saver ! Always good to have a back up . I pumped regularly and these lasted me a longgg time

They fit will with my Momcozy S12 Pump. the duck valves are a little longer then the factory ones but they work i just have to make sure they are all the way on when assembling the pump.

They fit and work nicely, after a while I change them cause they get loose and also stained.

This wearable breast pump whole bowl milk collector is great! It is easy to take apart & put back together. Cleaning is very simple. It fits my MomCozy S9 perfectly. I would recommend this product 100%. Also the price is very affordable! Lastly the picture of this product is 100% accurate.

Does not actually fit the Paruu P10. False advertising. Got a second pump to be able to pump more throughout the day while my normal one charges, got these to fit it said it was compatible. Does not fit even though it says it does.
