Wearable Breast Pump Parts Milk Collector Cup Flange 24mm Compatible with Momcozy/TSRETE S9/S10/S12 Breast Pump Replacement Parts Accessories, 2 Sets, Extra Duckbill Valve&Silicone Diaphragm

I bought these as a back-up set for my Mommed pump and they work great!!! The pieces fit together really nice, feel good quality, and you can't beat the price. Super happy and would definitely recommend.

These replacement parts fit perfectly. They are priced well, and come with extra pieces. Additionally they came with a little plastic container I repurposed to hold my babies teethers in the diaper bag!

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 :/

I have one of the older Momcozy wearable models (s9) and these silicone shield replacements work perfectly!

Great for having extra cups to reduce the amount of cleaning each day

I have the Opnmina hand free pump and the battery doesn't quite fit I have to push it down super hard. This spare part also leaks a lot, so be careful. I have literally cried because of how much breast milk I've spilled when using this spare part. I make just enough for my baby so it's very frustrating. I only use it in extreme occasions, honestly it's just better to buy the whole breast pump for $30 $4 more.

It’s what was needed but a little misleading that it comes with two sets of the small pieces and only one set of the flange and container.

The item is great! The only thing is that I thought it was a set of two but that’s my fault for not reading the description
