Wearable Breast Pump Replacement Parts Duckbill Valves 4PCS & Silicone Diaphragm 4PCS for Momcozy S12 S9, Original Part Accessories Replacement, Electric Breast Pump Part, BPA Free, Easy to Clean,8PCS

Great product, works well, size is accurate and is exactly as pictured.

The media could not be loaded. I was looking for a quality hands free breast pump that didn’t cost a fortune and came across this one. After reading reviews and researching other brands, I decided this was the best option. First week of bringing baby home I have used this pump and it works flawlessly. No sitting around waiting for the pumping to complete, you can do household chores, run errands, etc…while pumping discreetly, I have used it while in the car on the way to doctors appointments because I know by the time we arrive baby will be hungry. I LOVE this pump.PLEASE NOTE: when purchasing the $47 pump it’s only one, if you’re expecting two make sure to select that option. I totally did not pay attention to that and thought I was getting two for $47

I have the spectra caracups and this is a great replacement dupe for the spectra duckbills. Spectra duckbills are 14.99 for one pair and these are 9.99 for 3 pair. It does the job but honestly if you are an exclusive pumper they will not last long as I replace them every two weeks or so as I feel it’s losing suction.Update: I am not sure what’s happening but last few times trying to order the 6 pack of duckbills I keep receiving a pair of duckbills and a diaphragm. I am unsure if the company mislabeled their products or amazon workers are clueless. This has caused me to stop purchasing entirely bc I do not want the risk of getting the wrong item.

I am writing this review to share how satisfied I am with this single best pump. While I am nursing my son on one side I am able to freely pump on the other. I honestly have no complaints. It’s very easy to assemble and program. Take note that the motor at the top makes the pump top heavy so to avoid it falling over and spilling out your freshly pumped milk remove it immediately after you are done. The pump is not completely quiet but that’s expected but it also isn’t very loud at all. My son nurses and sleeps right through it. I searched through SEVERAL other options, reading many different reviews before making my final decision on this particular single best pump. I am very happy and overall this was a great buy!

These were ok but did not fit my breast pump

Perfect, for the price. I use nipple butter when it’s tight getting it into the flange.

If you like flanges that slowly rip your nips off & feel like sand paper while pumping, then these are the ones for you!Yes I bought the correct size, I’m sure! These are absolutely horrendous. & the fact that the company makes it impossible to return them just makes this purchase that much better. I should have just thrown my money in the trash, like I am these flanges.

If you are looking for a valve to fit the original momcozy s12 this is it!!I kept getting sent the valve for the s12 pro(from but the manufacturer and on Amazon) and it did not fit. Way too short.But this one definitely fits the original s12(not the pros!!!). It’s the longer valve. People says it touches but it does not touch the container. It’s the same as the original. It fits like the valve that originally came with the s12. I’m one happy customer finally!!
