πΌMy Honest Take: Which One Should You Pick?
π‘If you’re on a budget and want a no-frills wearable pump…
Go for the Momcozy S12. It’s reliable, gets the job done, and doesn’t break the bank. But prepare for a slightly bulkier fit and a bit more noise.
π‘If you’re prioritizing comfort, customization, and quiet pumping…
The Momcozy M5 wins hands down. It’s sleek, gentle on sensitive nipples, and feels thoughtfully engineered for everyday useβespecially for smaller-chested moms.
πDeeper Dive: How Each Pump Performs
βComfort & Fit
The M5 feels like a major upgrade in terms of comfort. It uses a more flexible, contoured design that hugs your breast naturally. It also comes with multiple flange sizes right in the box (17mm, 19mm, 21mm, and 24mm), which is a blessing for moms like me who don’t fit the standard 24mm. The S12, while functional, can feel bulky β especially under clothing β and the fit isn’t quite as forgiving.
πNoise Levels
Let’s be honest: nobody wants their pump to sound like a power tool. The S12 is a little on the noisy side, which made stealth pumping in the office a bit awkward. The M5, on the other hand, is super quiet β I could pump during Zoom calls without anyone noticing.
π§ΌEase of Cleaning
Both pumps are relatively easy to clean, with minimal parts. However, the M5’s closed system and simplified assembly make it slightly quicker to rinse and reassemble. That’s a huge perk when you’re doing this 4β8 times a day!
πBattery Life & Charging
The M5 lasts longer on a single charge, which matters when you’re juggling baby, work, and errands. Both charge via USB-C, but I found the M5 held up better over time with frequent use.
π§ͺSuction Performance
This one’s subjective. I got similar output from both pumps, but the M5 gave me slightly better letdown response, probably due to the softer silicone flange and added stimulation mode. If you’re exclusively pumping, that extra comfort goes a long way.

π€Verdict: Momcozy S12 or M5?
If I had to pick just one? The Momcozy M5 wins in almost every category β comfort, noise, design, and personalization.
That said, the S12 is still a solid budget pick if you don’t mind the extra bulk or slightly louder motor.
Final Word:
Pick the M5 if you’re planning to pump often, have sensitive nipples, or want a sleeker, quieter pump.
Go with the S12 if you’re pumping occasionally and want to save some cash.
