Hallelujah, they fit And aren't insanely priced.
I have the MomCozy S9 pro. These fit perfect!!! Im very happy with the quality and the price as it's been hard to find them on a single mom budget. I will absolutely be ordering more.

Fits my pump well
Unfortunately, my insurance stopped providing me with free pump part replacements. At the time, I was pumping 2 hrs a day and concerned with how much replacement parts would cost. However, these are a great deal for the amount of parts it comes with. They come with a small plastic box to keep them in too which is nice to have.

Compatible with MomCozy S9
This is compatible with the MomCozy S9 wearable pump! Changing the parts out for these increased the efficacy of the pump. Definitely recommend:)

Diaphragms work for S12 Pro
Duckbill flanges are not compatible with S12 Pro, but the diaphragms fit.

Came in handy
Came in handy, I didn’t use all of the pieces it came with but for moms who are breast feeding much over a year I think having extra pieces for your pump is a good idea.

Do not buy for s12
DO NOT BUY. They ruined my pump . $12 purchase costing me $160 on a new pump . It says they fit momcozy s12 pro and it’s such a lie because when I put it on and started my pump the milk got puddled up on the suction part and my motor sucked the milk up cause it to brake. They are obviously not made for this pump

Don't waste your money if you have momcozy S12 pro
The duckbills are too long and I wasn't able to get any suction. Waste of money

Schlechtere Leistung als mit dem Original
Leider habe ich ein Original Entenschnabelventil für die momcozy s12 pro verloren; im Shop selber habe ich nichts gefunden. Dieses Ventil ist leider nicht annähernd so wie das Original ( vielleicht im Aussehen), aber leider fühle ich (auch nach mehrmaligem Nachjustieren und neu ansetzen der Pumpe) nicht den selben Pump/Saugeffekt manchmal sogar keine Leistung - echt nervig.
