Great product for the portable breast pumps

The a great alternative to the mom cozy flange. Fits nicely my mom cozy s12pro.

These fit perfectly on Momcozy S12 Pro.

So I am over the moon, I bought the fetalplus hands free pump, and it came with 24mm silicone shields, however they do not sell bigger sizes I found out and I need 27mm shields, so I decided to try these and THEY WORK!!! I was so nervous to purchase because I was afraid they weren't going to fit, being no one say compatible with the fetal plus 3.0 pump, the only thing I had to do is cut the slit just a tad bigger for it to seal properly, and like magic works perfect. For any other moms that have the fetal plus get these and the small modification, it works great has same suction/ seal power thank you so much! I'm so relieved to not have to buy a whole new set up!!!

Works great with my mom cozy S9
