bliblo 5Pack Silicone Diaphragm & 5Pack Silicone Duckbill Valve Compatible with S9 / S12 / S9Pro / S12Pro Wearable Breast Pump, Electric Breast Pump Replacement Parts Accessories(10Piece Set)

Lost a piece to my Momcozy part and these worked! Thankful for the extra available parts.

These diaphragms do NOT fit Baby Buddha wearable cups! The product doesn’t claim to, but some reviewers said it worked, and mine does not, so trying to save others the time.

The clear duckbill and diaphragm are very noisy. The whitish looking ones are not as noisy. Hopefully they get better as they get used.

I never write bad reviews, but these duck bills pop off every other time I use the pump, and the only way to get them back on without sliding off again is rewashing them with soap. I keep my pump in the refrigerator during the day and wash it at night, so having to disassemble the pump right as I’m about to start using it, and rewash those parts is extremely frustrating

These do not work properly with my mom cozy. The membrane doesn’t pull up and release properly making my duck bill not release the milk and it backs up into the Falange. Waste of money.
