  • Feels like butter
Size: S (For 21-23mm Flange)
I got this for my elastic nipples and output. I don’t think it really increased my output dramatically but maybe like .5oz? But I will say that it I can barely feel it when I pump and it helps me have easier let downs! I got a size small and I use a size 21mm flange. And it sticks out a bit but still works great! ... show more

  • Game-changer for moms with elastic nipples
Size: S (For 21-23mm Flange)
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! ... show more

  • HEAVEN SENT
Size: M (For 24-26mm Flange)
I literally never write reviews .. but these pump cushions will be your BREAST FRIEND if you have elastic nipples ! My supply has almost quadrupled in 12 hours !

  • Nice product
Size: M (For 24-26mm Flange)
I wish I could give these 5 stars. They are soft and work like they should. I have elastic nipples and these helped out when placed in my spectra flange. The only reason I didn’t give these 5 stars is that they did not stay in the flange. When I was done pumping and I’d remove the flange from my breast and the cushions would fall off. I wish they would get stuck like other cushions/inserts I’ve used in the past. Other than that these are great. ... show more

  • Didn't work well for me, might work for you.
Size: M (For 24-26mm Flange)
So I have elastic nipples and have been having a very hard time with pumping and finding my correct flange size. I wasbusing 24mm and the swelling and rubbing was causing some serious nipple pain. I tried this thinking it would help. Ok so, my nipple felt less sore AFTER pumping but the rubbing DURINGA was almost unbearable. I thought these were supposed to feel better than the hard plastic but not for me. Now mind you, I have come to the conclusion that I'm probably a smaller size than 24mm so that could be where the problem lies. However since this product is non returnable, I an not willing to spend the money to buy the smaller size when there's a chance it'll be the same. Might work for you if you truly know your size ... show more

  • If you have elastic nipples BUY THESE
Size: S (For 21-23mm Flange)
I rarely write product reviews and was super skeptical that these flimsy, thin, silicon inserts would make a difference in my pumping but these are a GOD SEND. These inserts have prevented my pumps from tearing up my poor nipples. Before purchase my nipples were literally blistered and now I have pain free pumping! ... show more

  • Inaccurate size description
Size: S (For 21-23mm Flange)
I ordered the small and it says it fits a 21 size flange but it does not. It is more like a size 19. This is useless if it does not fit correctly. It is also non returnable. Read review to help assist in sizing if you choose to purchase this product.
