Size: M (For 24-26mm Flange)
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!

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!

Size: XL (For 30-35mm Flange)
After 3 kids my nipples are now much larger, making it very difficult to find pumping products for larger nipples as I am a 32 for my left breast and 30 for my right. I got the xl for 30-35 nipples after searching for weeks online for something that would fit because nobody seems to sell things for larger nipples. I was skeptical that this brand would actually work. However I started using these and they are great! They making pumping so much more comfortable with my spectra which makes me not dread pumping as much since I exclusively pump. They also help with my output of milk. Before I found these I was averaging 8-10oz per session now I’m averaging anywhere between 12-16oz per session. I also just recently tried these with my Elvie wearable pump because the biggest flange size Elvie offers is a 28 but I'm actually a 30 for my right nipple and 32 for my left. It was difficult for me to get more than 8 oz with the wearable pump before using this product and I had to pump double the amount of time, and it still would not empty my breasts. I decided to put these on the wearable pump just like I do with my hospital grade pump and wow the output increased to be closer to what I pump with my hospital grade spectra and less time pumping. Also great for elastic nipples!

Size: L (For 27-29mm Flange)
Just skip if you’re buying for elastic nipples. These say they are for flange sizes (21?) 24-27 I believe. I use a 27 and this does nothing. My nipple is pulled just as far in to the back of the flange as it was when I didn’t use it. It’s incredibly thin. They came bent because they are mushed into a box and don’t regain their shape, so if you don’t mind the lift in the front against your breast that won’t be an issue. I wanted to avoid a more expensive brand. I was hoping this would help with not stretching so far into the flange but these were about as useless as tossing some plastic wrap into my flange hoping it would work.

Size: 18 (For 24-25mm Flange)
I liked these at first, but I tried some other silicone flanges as well and realized what is amiss with these; 1- the frosted material makes it difficult to check for placement when using a breast pump. 2- the flange sets into the pump flange perfectly fine, but doesn’t stay in. Others I’ve tried have a small edge on the outside of the tube portion of the flange that keeps it in place in the pump flange. Personally, I prefer that, as it’s just a tiny bit easier to handle as you’re removing the Flanges. 3- this May be completely circumstantial and definitely not scientifically studied… But I felt like my pumps produced less volume when I used these flanges over others. I’m not sure why nor am I 100% certain of it, but it was a common enough occurrence for me to wonder. Neither of the above issues are deal breakers by any means, but when you’re pumping 4-6x a day, breastfeeding, working full time, etc etc, each monitor functionality makes a difference, so for me, these just didn’t do it.

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.

Size: 22 (For 24-25mm Flange)
I exclusively pump and so I use these inserts daily several times a day. I have not noticed any wear they still work as intended. Easy to clean, it’s comfortable. Something they hide from my eyes since they are clear but I always find them. Very satisfied value for money. Perfect fit. Gets the work done.
