Review on Nenesupply Pump Parts Compatible With Medela Breastpump Not Original Medela Pump Parts 24Mm Breastshield Valve Membrane For Medela Pump In Style Medela Symphony Swing Replace Medela Breastshield by Roger Sanders

These have been a lifesaver! On my third child, I finally realized I have been using the wrong size flanges all these years. I went through three sizes before I finally bought these. They are comfortable, no issues with pulling too much areola into the tube, they are the perfect fit. I don't mind that it's all one piece, as it doesn't hinder the cleaning process. My only concern was that I really had to shove the tube into it, to get good suction. My output has gone up by an ounce or two consistently after switching to the correct size. If you're like me and have struggled with breast pain from the wrong size flanges, do yourself a favor and try these out.
