Flange Inserts for Freemie Flanges (21 mm); Small Inserts for Freemie Collection Cups

Good quality. I purchased these to use with my Momcozy S9 pro - unfortunately they are too long, had to purchase another set in the regular/short version.

Got super frustrated with a lack of output with all the different flanges I tried from various pumps with my first and only found out after I quit breastfeeding that I needed smaller flanges. Bought these when trying for my second after using Medela sizing to estimate what size I needed. I've been using these for the past two months and what a difference! I usually get anywhere from 4-6 ounces with these after ten minutes of pumping. Totally worth it, and really not that difficult to remove for washing if you use a towel to grip and twist out like instructed. I also use Maymom hard flanges and duckbills and it's all super effective at emptying the breast and getting milk in my bottles. I rest easy knowing I've been able to supplement exclusively with pumped milk for my baby!

En mi caso las voy a devolver porque venían manipuladas, pero una amiga que las tiene me las enseñó y cumplen perfectamente su función

Does a great job, even turns me on a bit.

Using these on the Eufy S1 Pro as a substitute for the flanges that come with the pump. I was initially concerned that the flange would be too long as it touches the diaphragm but it’s not an issue. These are much more comfortable than the flange inserts that come with the pump and overall helped improve my output especially on the side with lower supply.
