Beast Pump Full Set Milk Collector Cup 24mm Only Compatible with Momcozy S12 Pro/S9 Pro Breast Pump, NOT for S9/S12,for S12 Pro/S9 Pro Wearable Breast Pump Replacement Parts with 24mm Flange

Really good option to replace patty's in my S12 mom cozy definitely helps when they are new to get the best suction!

These are nearly identical to the name brand, zero issues, easy to take apart and assemble, easy to clean, holds so much milk

Do not buy if you regularly use your Momcozy pump and want to be fully emptied. These are made with a cheap material and caused my pump to not fully empty me. I should have just spent a few more dollars and purchased the actual Momcozy parts.

I was told that duckbills shouldn’t leak when water is in them. Half of these do and half dont. Wondering if I got a bad batch now.

The Full Set Milk Collector Cup works great with my Momcozy S12 pro and even my Baby Buddah 2.0. The set is definitely cheaper compared to the OEM's replacement cups. The quality of the cups are pretty good and gives me about the equal same output as with my original OEM cups. Definitely would recommend this if you are trying to save some money.

This works perfectly with the Momcozy S12 Pro! It also works great with my Zomee Z2 as an extra cup set. The Zomee Z2 is my favorite pump out of all the pumps I have. These cups can be used with some adaptation; they can fit the Zomee Z2, the Motif Luna, and the Spectra. What a great deal on a single cup. It would be even better if you could purchase a set.

As expected. Replacement parts work well.

They fit my pump perfectly. It was a steal!!
