PDFans 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

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.

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 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.

Great product, but didn’t realize that you only get one cup with an order. If you need a pair order 2!!
