The instructions read to insert into the 24 mm flange which resulted in no suction. Tried inserting into the 21 mm flange and the suction was great. Definitely worked much better. **Q: Which works better, the flange with the 17mm inserts or the 17mm flanges? I’m wondering if the softer material might get better results?** A: Freemie doesnt sell 17mm flanges. Their default is 25 mm. Maymom sells 17mm flanges. I had both. Liked both. Same results. Choose whichever is more convenient for you. I ended up loving the Freemie cups with the Maymom inserts. **Q: Is it compatible with Medela Swing?** A: Yes **Q: Can I insert in a 19mm cups or it’s only for 24mm cups?** A: They will not fit in a 19mm. They’re made for 25mm, but will fit into a 24mm...however, when inserted into a 24mm flange they stick out a bit but it doesn’t affect suction. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Parfait *by O***O on 11 December 2023* S’adapte très bien sur le mom cosy s12 ### ⭐⭐⭐⭐⭐ Easy to use *by V***O on 20 June 2021* No struggle to slice in flange ### ⭐⭐⭐⭐⭐ Awesome! *by M***. on 26 November 2025* These are awesome for pumping! They work great, and fit perfectly. The annoying part is not being able to see the milk release as they are not see through, which I tend to find satisfying lol! But no complaints. I used these for the BabyBuddah pump (from the states) which was an amazing experience for pumping! ## Frequently Bought Together - Maymom 17mm Flange Inserts (Long) Compatible with 24mm Medela PersonalFit Flange, Spectra Flange, 25mm Freemie Flange(Restricted Freemie Cups), Compatible with Momcozy 24mm Cup (S9, S10, S12) - Maymom Flange Inserts 19 mm for Medela, Spectra 24 mm Shields/Flanges, Momcozy/Willow Wearable Cup.
