Full Set Milk Collector Cup Compatible with Momcozy S12 Pro/S9 Pro Hands-Free Breast Pump Wearable,Upgrade Duckbill Valve for Original S9 Pro/S12 Pro Replacement Pump Parts(NOT for S9/S12),Flange 24mm

Bought this for my wife because she accidentally broke one of her original ones and this one worked better! Great buy and exactly what we needed!

I got this as extra cups for my momcozy S12 and they work really well. They do not leak and setting up the cups is way faster than the cups that came with the breat pump. Just make sure you have extra nipple flanges or you will need to buy extra. These cups do not come with the nipple flanges so IT WILL LEAK if you try to use it without the flanges. I liked it so much I bought a second set of cups so my pump is always ready to use. It's one cup per order so you need to buy two if you want to use for both breasts at the same time.

Trash. These appear to be compatible with the momcozy s12pros but they aren’t a perfect fit making the suction non existent. I am an oversupplier and used these once and barely got 2 oz total. This isn’t saving money because you’re going to have to get the momcozy ones anyway since these don’t work.

It feels a little more rigid than the actual cup/parts that came with my momcozy s9 pro but I have had successful pumps with it. It has been easier having a second set of cups/parts so I can rotate between the two and not have to rush to clean and dry right away. It’s also made it easier to be able to pump every 2-3 hours having a second set because my baby often dictates what I have time for and the cleaning and drying of just one set usually doesn’t happen. Now I don’t have to worry right away.

I think this product is great and works well! I was slightly hesitant with the reviews, but glad I decided to try it anyway. It fits my momcozy s12 pro, it is a little harder to snap on to the motor than the momcozy brand, but still works just as well and empties me the same, if not better! I haven’t had issues with leaks. You do have to press a little harder to ensure the top is snapped on well, but it’s really easy to see if it’s snapped on properly. Overall, does the job and saves you a couple bucks!

It’s hard to get a good suction. You have to mess around with the placement for it to work. It also only the one pump part instead of a pair. So definitely make sure to buy two.

Fits the s12 pro. Actually think it’s easier to put together than the original one

These parts for perfectly for replacement of momcozy s12 pro, the battery does latch on a little different but does not leak, and it feels less bulky in a way. I originally bought two sets to help with cleaning every pumping session and these are actually easier to clean!
