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 Steven Bush

I bought these to help size down the Legendairy Milk silicone collection cups. The write up doesn’t list them as compatible, but I needed to try something. Fortunately, these fit perfectly! Once you insert these into the 24 mm flange from the kit, these fit seamlessly and comfortably. Having a perfect fit also allows for better milk pumping efficiency. They are very comfortable, with no rubbing.
