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.

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:)

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.

IT WILL DESTROY YOUR MOTOR DO NOT BUY
Says it’s compatible with the mom cozy S9 pump. The silicone membrane did not seal causing milk to get sucked into the motor immediately, destroying my pump. I shut it off as quickly as I could but it was too late. There are tons of other reviews saying the same thing. I have a one month old and now I’m down one pump and have to shell out money to replace. This should be illegal.

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.

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.
