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.

Work very well. No issues

I purchased two of these as they are sold individually. They looked just like my current tsrete cups so I threw away the packaging thinking they’d be the same. Sadly they don’t fit with tsrete and therefore does not give the same output. It’s not worth it. I usually can pump 4-5 ozs with this I barely got 1 total. Very frustrating. It seems it doesn’t give the correct seal therefore there isn’t good suction.

I didn’t realize that this didn’t contain flanges for both sides! So just know that you’ll only get one if you order this/will need to buy two if you want to use your pump on both sides.

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.
