So, about the Momcozy S9 Pro breast pump and leaks—our research shows it's kind of a mixed bag. Some people don't have any problems, while others occasionally notice some leakage.
The manufacturer stresses that getting the right flange size is super important to prevent leaks and make pumping more comfortable and efficient. The pump comes with a 24mm flange, but you get inserts of different sizes and a nipple sizer to help you find the perfect fit. This is supposed to help cut down on leaks and improve the pumping experience overall.
From what we've found, lots of folks say that putting the pump together properly and making sure everything is aligned right can really help with leak prevention. Trying out different flange sizes and always checking for a good seal also seems to be key.
So, yeah, while there are some reports of leaking, using the right size flange and making sure everything's put together correctly can make a big difference.
If you keep having issues, it might be worth reaching out to Momcozy's customer service or trying a different flange size to see if that helps.
