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.

Does not collect much and leaks
This collected next to nothing for me and leaked what it did collect, would not recommend to get with insurance and definitely not purchase out of pocket.

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.

Leaks milk
Multiple times my milk just leaks from the bottom and before I realize it I've lost ounces of milk!!! It just hurts to see all the wasted milk. I wish I never bought this pump

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!

Technically portable but will return
It is indeed portable but there are a few things that made me return it. It is very loud like the regular non-portable pump I had. The outer suction makes it very easy to leak or waste milk when the session is done and you are finished and if you don’t have the right flange size (this only comes with two smaller options), it is pretty uncomfortable

Good while they lasted but broke after 5 months
After only 5 months both the battery pack parts do not work one just started randomly pausing then going again and the other just doesn’t have any sucking power. When trying to contact the company I received 0 response I would not invest this kind of money in them:

LOVE
After not having a pump when having my son I desperately needed one. I was torn between the M5 and the s12 pro i got the s12pro and I absolutely love it! first time I used it it emptied me out better than the one I used in the NICU!!! I'm someone who needs longer pulls and stronger suction and this pump is PERFECT. I would say after a long day of pumling the highest level is a bit much but that's understandable. I do with the battery life was a bit longer but I gets me through a whole day so that's nice lol. I also do have a larger chest and these are pretty bulky. if you are looking for discreet I would choose a different I'm a stay at home and usually don't pump anywhere in public so i dont mind. I used this pump while on a long drive and it was easy to use and not distracting or in the way.

Love it!
Received my pump yesterday and I already wish I had got it sooner! Being hands free makes pumping so much easier. Worth every penny I love it!

So convenient
It works so well! Convenient to be hands free when pumping and the pumping level is high and efficient! The only little downside is that it does have many parts to cleanð
