4pcs Silicone Diaphragms Compatible with Momcozy Mobile FlowM9, Mom Cozy M9 Replacement Accessories, M9 Breastfeeding Parts, Replace for Momomzy Diaphragms

Even better than the original ones! Work perfectly fine.

Good replacement when many backup parts

The diaphragms work great. Some of the duckbills worked better than others, but overall they’re pretty decent. This set seems to be decent quality overall and a more cost effective replacement set for the M9. I’d buy it again.

Fit the momcozy M9 pumps perfectly and are actually more durable and less likely to tear than the OEM version.

The 6 of the 8 duckbills are terrible. They fit just fine, but the slice on the bottom is too wide and prevents proper suction. I wish Momcozy would start stocking duckbills again!

Three of my duckbill valves have an open gap that does not close so I am unable to use them. I gave it a try but they never allowed milk to be expressed. The rest was great though and works fine. I don’t see these lasting 3 months

Was waiting for Momcozy to have restock of replacement parts for my mobile flow m9, and after a month of checking amazon, came across these replacement parts. They work perfect for my pump.

Muy buenas se adaptan bien al extractor
