8pcs Duckbill Valves and 4pcs Silicone Diaphragms Compatible with Momcozy Mobile Flow M9, Mom Cozy M9 Replacement Accessories, Breastfeeding Parts, Replace for Momomzy Valve Diaphragms

Amazing. Fit perfectly best dup out there

Great replacement parts and fit perfectly

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.

Like the name brand! Seriously. I had no issue getting these to fit my momcozy pumps. I wanted to keep things fresh and clean and having cheaper alternatives has been a blessing. They fit like the ones that come with the pump. No issues at all and the price is great!

The diaphragms were a perfect dupe! The duck bills; however, make me want more from them. They fit fine, but the slit across the duck bill were a bit off centered? I’m fairly sure that’s my issue with the product. It feels like they’re getting worn down a bit more quickly, so I was replacing them again in just a week- mind you, I use my M9 pumps 3x daily when I work. So if we do the math- I had to replace them after using them 21 times, whereas I didn’t need to replace my original Momcozy duck bills for a full month and a half. If you’re gonna get these, get them for the diaphragms, not for the duck bills

Even better than the original ones! Work perfectly fine.

Took me a while to find the right fit for my pumps these were them! For the momcozy hands free

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!
