Q: Are there multiple flange sizes or just the 24?

submitted by FlowerLoveFlower - 2 years ago

  • A: Multiple. Comes with the 24mm and then 3 different inserts sizes. The inserts are 17mm, 19mm, and 21mm

    submitted byAlexis - 2 years ago

  • A: i don’t see any real difference between the s9 pro and the s12 pro what’s the real difference

    submitted byj - 1 year ago

  • A: I just ordered one of these and there are no inserts included. Only the size 24mm flange.

    submitted byEm - 2 years ago

Q: Is this pump considered hospital strength? Also, can a flange size of 28 or bigger than 24mm be purchased for it?

submitted by V - 5 months ago

  • A: Thank you for your questions. The pump comes with a standard 24mm flange. The largest size available is 27mm, and you can choose a larger one based on your needs. This pump is designed for personal daily use and is not classified as a medical-grade device. It is made with high-quality, skin-friendly silicone and food-grade materials.

Q: Can the parts be washed in the momcozy washer/sterilizer?

submitted by Sam - 6 months ago

  • A: Yes, the parts can be washed in the Momcozy washer/sterilizer. Just be sure to check the care instructions for any specific heat or cycle recommendations, but generally, it's perfectly fine to use. Let us know if you have any other questions!

Q: Does it auto stop pumping when it senses it's full or do you have to pay attention and manually stop it to prevent overflowing?

submitted by Twinmom - 1 year ago

  • A: Hi, the S12 Pro-K pump does not have an overflowing reminder. Each session lasts 30 minutes, and you need to manually turn off the motor to prevent milk from leaking.

    Super honest review!!!!!!

    I received this as a baby shower gift. I dislike the bulkiness, it doesn’t show how long you been pumping,but so far the s12 pump has be feeling super empty after a 15-20 min session!!! Which is crazy bc I usually use my pink spectra and I get max 2.5 oz and with this one I get anywhere from 4oz to 5 oz EACH side!

    Little output

    I have three pumps - Spectra S1, Medela Pump in style, and this one. I used to bring the S12 to work with me about 7m PP, but then it randomly started not extracting milk in the same way as my other two pumps. I leave the Medela at work now and use the Spectra S1 at home. I stopped using the Momcozy S12 for a few months after trying again at home. I pumped for 30m and had less than 1oz. I put on my spectra and had 4oz in less than 10 minutes. Tried one last time today and unfortunately got the same outcome - less than 1oz with the Momcozy S12, put on my Spectra S1 and got 4oz. Same thing as other users have indicated in terms of time, readjusting, taking apart/putting back together, etc. It's so disappointing because it used to work well, but it can't be a supply issue if I'm able to produce more milk with my plug in pumps immediately after using this one. It would 100% be my go-to pump if it were able to provide the same output as my other pumps because it is SO much more convenient, but definitely not as comfortable.

    We’re truly sorry to hear that your S12 Pro is no longer providing the output you previously experienced. We also appreciate you sharing such detailed feedback about your experience. You may try a few simple checks: • Make sure the flange size and positioning are appropriate and that the nipple is centered in the flange tunnel. • Please check that all silicone parts, including the valves and diaphragm, are properly installed and fully sealed. • Inspect the valves and diaphragm for any signs of wear, damage, or deformation, as these can affect suction and milk output. • If possible, try replacing the valves and diaphragm with new ones and test the pump again. If the issue persists, we’d really appreciate the opportunity to look into this further and help find a suitable solution. Please contact our after-sales team at support@momcozy.com and attach your receipt/proof of purchase.

    0/10 Would NOT recommend

    I actually hate these pumps with a passion. I own 4 breast pumps, and these are my least favorite by far. There has been several times I've gone to use these, and cannot get one of them to suction. Even after taking them apart and reassembling several times. There are too many parts that have to be assembled. Even when I can finally get them both working, they tend to be painful without much suction. My other wearable give me a similar output to my wall pump but with these im lucky to get half.

    LOVE this pump. It’s so easy to use, super easy to assemble and figure out what settings works for you. The replacement parts are really affordable. The battery lasts a long time. It’s super comfortable. It is a bit bulky, which does suck, but still one of my favorite pumps.

    I wish I listened to the reviews that claimed this pump is not good for bigger chested women. because it absolutely is not. I got this pump because i need replacement parts for my M5 and this pump was on sale and it was cheaper to buy a whole new pump than parts and i had been wanting a second set of wearables anyway since i exclusively pump. I would never buy this pump again. The suction is horrible, takes double the amount of time to get the same output compared to what my M5 and spectra do, and it leaks regardless of it being put together properly. extremely disappointing. I can wear my tightest sports bra and it still doesn’t feel like these pumps are doing anything.

    Hello, I'm sorry to hear that your breast pump is not working properly. Breast Pump Quick Troubleshooting: 1️⃣ Check assembly & parts—Make sure all valves, membranes, and connectors are correctly installed and not damaged. 2️⃣ Inspect tubing—Ensure tubes are airtight and free of cracks, bends, or blockages. 3️⃣ Flange fit—Use the correct size; a flange too large or small reduces suction significantly. 4️⃣ Suction & power – Make sure the pump is fully charged/plugged in and on the proper suction setting. 5️⃣ Clean & dry – Milk residue or moisture can prevent proper suction. 6️⃣ Try replacement parts—If problems persist, replace valves, membranes, or tubing as needed. **If the product is no longer working properly, please contact our after-sales team at support@momcozy.com and attach your receipt so that we can quickly handle it for you.

    Probably the worst breast pump on the market

    These reviews have to be fake. There’s no way this awful breast pump has a 4.6. Mine stopped working within the first two weeks also, one of the chargers to the motor caught on fire. I thought my house was having an electrical fire and didn’t realize until the end of the night that it was actually from the charger from the pump. Not only am I disappointed with the performance of the product, but it is proved to be dangerous. I absolutely would not purchase and I absolutely could not and would not recommend.

    Best Pump on the Market!

    Motor is a bit bulky and not very discreet, but other than that this pump is perfect! Strong suction, silicone flange, and large storage make this the best pump I’ve tried by far! Great for large chested women (I’m an F cup for reference). Very reasonably priced for the quality

    Just Ok. Another model might be better

    Got this pump to take to work. Started using while on maternity leave. After 9 weeks one battery stopped working. I had the manufacturer replace. Now 5 months later the other stopped working. Hasn’t even been 6 months of continuous use and already problems. I have another pump I use at home. The protection plan is difficult to use. Would not recommend or buy again. May try another model from the momcozy.

    Ehh

    It was very uncomfortable to use. The suction was weird and half the time it wouldn’t work. Leaked milk every where no matter how well the seems were secured. Was not a fan of this pump, I wouldn’t waste your money.

    Excited to try!

    I haven’t had a chance to try this yet but I have a feeling I’m going to love it!!! I bought the additional coverage (2 year warranty) just in case one of the pumps goes out (based on other reviews). This pump only comes with 2 standard flanges (19mm and 21mm). If you are any other size you’ll need to purchase separately!
