Flange Inserts 19mm for Medela,Spectra 24mm Shields/Flanges,Compatible with Momcozy S12 Pro/S9 Pro/S9/S12 Wearable Breast Pump,Reduce 24mm Nipple Tunnel Down to 19mm,4PCS

Perfect fit into medela flanges

I ordered this because the set that I had bought had some that was broken and instead of replacing the whole kit, I just bought these and saved a few dollars in the process. Easy to install. Attached with ease. Perfect fit.

They work with many types of 24mm flanges; I've used them with the regular spectra, the wearable spectra, the baby buddha, and the manual medela. Easy to clean, but sometimes can keep a residue from whatever you use for a pumping cream (it's probably because I use regular coconut oil), but very easy to rinse or clean the residue off. I use these daily since buying them, I highly recommend them for people looking for a cheap and functional set of flange inserts. Also, they're both dishwasher safe and sterilizing steam safe.

These worked well for figuring out what size flange was most comfortable. They only have one of each size, so don’t work as well for pumping after you know which size unless you get two sets of 5. I’d only give 4 stars because these aren’t long inserts, so when using the willow 3.0, nipple could extend past the insert so that it was hard to remove after pumping. It still made pumping much more comfortable though.

I used these in my 24mm Medela cups! works great!

I haven't seen a difference in my milk supply and milk gets stuck in between the insert piece-- I use the fridge hack so this makes me nervous because that's a lot of stuck milk to pump ontop of. They wash easily and hold up in the sterilizer, I may need more time pumping with them over time.UPDATE: have used these more, and they just don't work as well as a full flange. For me, they mess with the suction power on my Spectra. Once you find your flange size order a full flange, the inserts are nice just to figure out what you need.

Works great with multiple of my pumps

These inserts definitely seem like they helped my milk supply! They’re soft and easy to insert into my flanges.
