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 Craig Pears

Before buying I read a lot of review and cautioned to try. I too can relate because my size is smaller and I thought I'd give it a shot. I used these with my Medela Sonata 24mm for about 2-3weeks pumping 2-3 times a day while at work. I work full time 5days a week and my little one will be 1yrs old next month. At 1st they were phenomenal! I didn't have a problem with milk getting lodged between the cups. Insert was easy in and out for cleaning. I would clean my parts after each use and air dry.As the days went on after week 1, I saw a decline in my outlet on pump 2 & 3. I stopped using these and pumping altogether for a few days because I got blisters and my nipples were ripped on the bottom. It was very painful to breastfeed my little one with the bruises and my supply suffered as well.Needless to say, I will not be using these anymore.
