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 Andre Young

I'm confused by the reviews that say these inserts don't work with the Willow Breast Pump's reusable milk containers. I finally bit the bullet and tried them. The Maymom inserts work perfectly with both the milk bags and the reusable containers for the Willow Generation 3 pump. I pumped the same amount of milk I usually do, had the same degree of comfort, and now I'm not going to have to spend nearly as much money for the milk bags. I've included a photo of how the Maymom insert fit in the reusable container's flange and the milk I was able to pump with it. These inserts are wonderful for moms with smaller nipples. I highly recommend them.
