Full Set Milk Collector Cup Compatible with Only Momcozy S12 Pro/S9 Pro Wearable Breast Pump,Duckbill Valve Updated with Free Rotation,Extra 5pcs Flange Inserts,NOT for S9/S12,Replacement Parts,24mm

I needed a second set and this did not disappoint! It even comes with different flange adapters.

You have to be very careful to not stretch or bend over or the bottom of it will pop off and you’ll have milk all down your shirt and everywhere

Don’t spent your money using others, this is the real one . I bough it for my wife and she loves it

It says "full set" and I took that to mean a SET of TWO. Cuz, you know, one for each side. Since the momcozy mostly comes in a set of TWO. A FULL SET, if you will. But no, it only comes with one cup set. Sooo you need to buy 2 to be able to fully pump both sides at the same time.

These are not double sealed like the original momcozy collection cups. They get the job done, however it’s ridiculously easy to unseal the flange and empty the cup all over yourself while taking them off. I’ve done it several times, and even when I’m being super self aware and careful, I still end up spilling milk. You’re better off just buying the actual momcozy brand replacement collection sets.

I have a Momcozy S9 pro, and love it. I bought this backup set or collection cups to help with dishes… but they do not work the same as the provided cups. I can’t figure out why, as they appear almost identical. But I can only get 1oz using them, where I normally get 7 oz. I would have been better off buying a whole new pump and cups from Momcozy
