Game changer
I had the momcozy breast pumps and I also had a freemie. I didn’t like the freemie cups and I got okay output with the momcozy pump.  So I decided to try to use my momcozy cups with my freemie pump and this little piece made that possible and it was a game changer for me. My output increased and I got more milk than I ever did with each of those separately. It’s definitely worth trying out.
