Review: Game-Changer for My Pumping Routine with Eufy S1 Pro! - I recently started using Mompmuri flanges with my Eufy S1 Pro pump, and they’ve truly transformed my pumping experience! I struggled for a while with discomfort and inconsistent output, but switching to these flanges has made sessions smoother, more comfortable, and more productive. From the moment I tried them, I noticed a better fit and seal, which immediately improved suction and efficiency. The design feels gentle yet effective no more pulling or pinching, even during longer sessions. I also find that they help with milk letdown; it seems like my body responds faster and more fully compared to the standard flanges. Another thing I love is how easy they are to clean and assemble with my Eufy pump. They feel sturdy and well-made, which gives me confidence I’ll be using them for a long time. Overall, the Mompmuri flanges have made pumping more comfortable, efficient, and even a little more enjoyable. If you’re using an Eufy S1 Pro and want a better fit and improved output, these are absolutely worth trying!
Review: Game-changer for moms with elastic nipples - These things are amazing! Pumping has been a very painful experience for me, to the point where I wince and feel my body tense up before I turn on the machine. No matter what flange size I’ve used, my whole nipple and areola get sucked into the tube. I’ve tried all available flange sizes, pumpin pals, and nothing helped. My output has been suffering because of the pain. I tried these cushions out and I got literally double the output of my usual pumping session! The cushions fit easily into my medela flex for flange. They’re are not completely clear so it makes it tricky to know if your nipple is centered in the flange. I managed to get a good placement on the first try, and my areola stayed almost completely outside of the tube for the entire pumping session! I had the occasional pinching sensation but no discomfort after I stopped pumping. Compared to the pain I had during and after pumping before, it’s barely even noticeable. If you have elastic nipples and pain when pumping, I would highly recommend trying these out!
