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

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.

Love these, bought as extras so I’m not washing 1000 x a day.Works perfectly with my mom cozy 12 pumps

Was missing the most vital part that connects to the pump motor. Not as advertised. I am annoyed with myself that I ignored the reviews and now I have to return the item. See pic as to what I received which is not what is pictured in the ad

I was under the impression that this was a full set so that I would get 2 cups and only received one haven’t used it yet so not sure if it is even compatible with my S12 Pro, which some of the review said it’s not. I wish I would’ve read the reviews before purchasing overall really disappointed.

I honestly like the fit of these cups more than than the collection cups that came with my momcozy. I bought these so I didn’t have to wash the parts constantly, and had a “back up”. Easy to wash and easy to attach the battery packs.
