Wearable Breast Pump Accessories Milk Collector Cup Replacement Parts Flange 24mm Compatible with Mommed TSRETE Missaa Mumgaroo S21/S19/S18 Pump, Bonus 1pcs Duckbill Valve&Silicone Diaphragm

Great product that really works with the momcozy S12 (not S12pro).

These are great, they worked well with my imani wearable pumps. Also so helpful that I can use these instead of entirely buying a new pump or parts that are super expensive.

I was skeptical of buying aftermarket pump parts, but I shouldn’t have been! These fit my Momcozy S9s like a dream, and the suction is great. They are also compatible with inserts (not included), so don’t worry too much if your flange size isn’t listed—you can alter it.

It has some weird extra lip that makes it so my machine for pumping doesn't seal. I of course didnt notice until I used them. (I ordered 2)So Im very bummed. Usually I use my machine on a 1-3 setting but with these not sealing in I have to go up to an 8 which now super drains the battery and makes my life harder! I need to pump 4x when Im out and about and now I dont have the battery life to.Im still on maternity leave and broke af. Cant return these bc theyve been used and clean. Super waste of money :/

They fit well on my eufy pump.

Bought these to replace the 27mm flanges the mommed S21 came with and it fits perfect. The quality feels the same as the ones that came with the pump as well.

Worked great until they started leaking not a big fan didn’t have very long before started leaking

Worked out great fit my wearable pump snuggley
