Momcozy M9 Replacement Parts Kit – M9 Breastfeeding Parts,Valve，2 Pack

Great replacement parts! I did find that these new, updated parts don’t work as well with the original flanges of the mobile pumps, I have to pair them with the updated flange for them to function correctly. Otherwise the suction is weird. But maybe it’s just me not using them correctly. I like them better than the original parts. Momcozy has amazing customer service, so any questions we have they answer quickly and well.

Trash. The new duck bills do not work at all. It does not transfer the milk into the cups and so it spills and doesn’t express milk, rendering the pumps completely useless. Why make a new product that does not work?!! Especially for pumping moms that NEED their breastmilk expressed, we can’t take a chance and risk lowering our supply. Did they even check their new design? Is it lack of quality control? I seriously cannot fathom why make a new completely failure of a product to replace the old design that worked? How am I supposed to use my Momcozy pumps now if the replacement products that I need to replace don’t work??!

I’m so happy they sell this individually! Cause I broke mine before started using it

The pump itself is great HOWEVER be aware of your replacement parts. The duck valve is NOT the same as the original. The pump (white part) isn’t either. This creates difficulty pumping, either the seal not being tight or the milk gets backed up into the pump. This has made my supply go down. The company needs to go back to the original or have a different color per update. Notice the size is different too (shorter is the original)

Real deal but took forever to get. But they do last much longer than wall pump parts. I just wanted extra.

Do not purchase these for the M9. These were advertised as working replacement parts for the Momcozy M9. I used them as directed. However, they did not work, failing to create a seal on the pump that would channel the milk into the container. This resulted in milk being spilled all over my clothes and the loss of several ounces on each side before I realized that they were not working. A complete waste of money and a loss of precious breastmilk when I just barely make enough to feed my son. Stay away from these.

Works better than the pink ones that used to come originally. Doesn’t leak.

Good replacement for my old m9 duck bills. I didn't like the packaging as they came stacked together and it warped the duckbill, though it doesn't seem to have affected how it works.
