Review on Maymom 15Mm Flange Insert Compatible With Elvie Single/Double Electric, Elvie Stride Cup (24Mm), Compatible With Medela PersonalFit Flex Shield, Not Original Elvie Replacement Pump Parts by James Arellano

So these did fit into my momcozy pumps HOWEVER they don’t create a perfect seal to the flange so Milk does get trapped underneath (if ur milk OCD like I am you can really carefully try to get the milk out when u take the parts apart to clean). U really have to press these hard into the flange upon insertion to create a good suction. I am however returning my momcozy so I’ll be retuning these as well
