Okay, so I've been using these Momcozy M5 replacement parts for about a month now, and here's the real tea ☕
First off - MAJOR cost savings! Like hello, why pay $100 for original parts when these work just fine? The set comes with everything you need: different flange sizes (super important!), duckbill valves, and those little silicone diaphragms. I was skeptical at first but they fit my M5 pump perfectly.
The comfort level is actually better than I expected. The food-grade silicone feels nice and soft - no weird smells or anything sketchy. And can we talk about how convenient it is to have multiple flange sizes? My nips have changed sizes like three times during this breastfeeding journey (who knew that was a thing??).
Now for the not-so-perfect part: One of my diaphragms fits slightly looser than the other. It still works, but I do notice a tiny difference in suction. Not a dealbreaker for me since everything else works great, but worth mentioning.
Pro tip: These are SO much easier to clean than the original parts! The anti-backflow design actually works better in my opinion - no messy milk spills so far (unlike some reviewers experienced).
Final verdict? 8.5/10 - would definitely recommend to any pumping mama looking to save some cash without sacrificing quality. Just maybe check all the pieces when they arrive to make sure everything fits snug!
