Great dupe
I have been struggling to express much and didn't think about replacing the parts. Get alot more milk now and they fit perfect with my momcozy s12 pro.

Too big, not suitable for use
Good quality material but too big for my pump! The duckbill valves are too long and the diaphragms lip is too deep! Can't return so a waste of money 😢
