Compatible with Medela Freestyle, Harmony, to Reduce 24mm Down to 15 mm; 2pc/Each : Baby Review: So Comfortable! - I’m in my 3rd baby and I’ve tried a bunch of breast pump inserts, but these are hands-down the most comfortable I’ve ever worn. The material is so soft and smooth — none of that annoying sticking or friction I get with plastic or other silicone type inserts. I use them with Eufy wearable pump— no friction, no irritation, just pure comfort. Highly recommend if you’re over wrestling with discomfort. They offer smaller sizing which is extremely helpful if you need those sizes. Total game-changer! Review: Must have for small n*ps - As a first time mom, I knew literally zero about pumping. I had no idea that the parts I got with my Spectra were WAY too big for me and sadly used them until I was in too much pain. Even if you buy other smaller flanges, they don’t account for the slanting in part so your areola is going to get sucked in still which is not a comfortable pumping experience (I learned this the hard way after time and money spent). These are the ONLY things that work for me. They account for sizing down the flange tunnel and the funnel part. I ended up buying a second pair and cutting the first ones down for my Elvies. ## Features - Maymom 15 mm inserts (Long) compatible with Medela PersonalFit/Spectra 24 mm shields.

Mine is losing its shape and so the ends are pinching me bad.** A: I boiled mine to sanitize them when I first got them. Seemed fine. **Q: If i measured 15mm would these be correct or should i purchase a 17mm insert?** A: I believe it depends on which pump you are trying to get. Willow needs exact sizing, I’ve heard to go up in spectra. I bought 15 and 17 and use whichever one was more comfortable, which was the true to size, 15s. Hope that helped! **Q: If anyone used these with momcozy s9 how well did they work??** A: They work very well. I used them in the 24mm momcozy **Q: Will these work for the momcozy ?** A: Yes they do ## Customer Reviews ### ⭐⭐⭐⭐⭐ So Comfortable! *by B***Y on September 5, 2025* I’m in my 3rd baby and I’ve tried a bunch of breast pump inserts, but these are hands-down the most comfortable I’ve ever worn.
