10pcs Breast Pump Replacement Parts for Momcozy S12 Pro/S9 Pro, Include 6pcs Silicone Duckbill Valves and 4pcs Silicone Diaphragms BPA-Free Wearable Breast Pump Accessories

Ease of cleaning, fit , and great value for the money

Not compatible with momcozy S12 pro. The duckbills are too long.

Great set of extra parts, both the duckbill valves and backflow protectors. Work well and good to have as back ups, especially if you pump exclusively.

Great replacement part, this part needs to be replaced every so often to get a great suction and remove more milk, this are a great value and works very well with my name brand pump. Easy to clean and holds up well in my sterilizer
