This review is going to be, well, probably not what you’re expecting. By the look of this pump, the technical abilities, and sleek contour, you may be surprised to learn that this is my least favorite Momcozy pump that I’ve ever put to the test. I have tried and regularly used at least eight Momcozy pumps, but the Momcozy Mobile Flow M9 takes the cake for the worst of them all. Let me give it to ya' straight and lay it all out in the review ahead…
I wish I could say that I used this pump on repeat to give you the best, most experienced review possible - which is honest to God how I compose reviews. I like to use a pump pretty regularly for some time, more than a month usually, to gauge and deliver my best, well-rounded review. The problem I have found with the Momcozy M9 is each time I use it I damage my nipples and leave blood behind in the flanges.
Unfortunately most times I’ve used this pump for a full 30 minute duration I’ve been equally disappointed with both bloody nipples and leaking containers. We will get to the leaking soon... What makes it so difficult for me to keep using these pumps for full sessions is the fact that I still need solid nipples and I still need to adequately move milk to feed my baby. When I endure this damage brought on by the M9, it affects my ability to feed at the breast and pump. For obvious reasons, this isn’t something I can deal with regularly.
Due to the results of my using this pump, it's been difficult to take it the full distance in testing because it drew blood most times. Each time I use this pump I find myself waiting to spring a leak or draw blood. So let’s talk about why that may have happened.
If you’ve read any of my reviews you know I’m a pushover for silicone flanges. I love them, I have elastic tissue, AKA elastic nipples, and I found six years ago that silicone was a deal breaker for me. It’s been six years and four pumping journeys so far that I’ve been a devoted silicone flange user, so when I saw these flanges, similar to the M6, I got excited- kind of. It wasn’t until I looked closer and realized .. once again, similar to the M6, these aren’t full silicone flanges. There’s a silicone buffer before your nipple goes full plastic tunnel. Momcozy calls this material soft and hard silicone, I have to disagree. When I think of silicone I think of soft and comfortable, that’s the whole point- right? So this whole hard and soft composite silicone flange thing, well it’s just not doing it for me. This is even more apparent every time I take the flanges off- cue the blood. Don’t get me wrong, I don’t lose a nipple every time I use this pump but I still draw blood and well, that shouldn’t be happening. I blame the blood on the transition of the materials, it raw dogs my nipples and leaves them bruised and needing some TLC. I’m sorry, but these ‘silicone’ flanges aren’t doing it for me, they’re far worse than the M6 flanges.. but when comparing the two- I’d pick the M6 any day over the M9.
Now for construction. Considering the M9 is one of their more recent pumps I’d expect easy assembly. WRONG. This pump remind me of a jigsaw puzzle. I don’t mean to get sassy because there’s a lot of things I love that Momcozy puts out but these pumps really are far from their best work. The first time I assembled these cups I was questioning which part went where. Why so many parts!? It’s a no for me, with six parts not including the motor, it’s kind of a pain in the butt to assemble. Like anything, with redundant use, I’m sure it gets easier and faster. But why, why do we have to deal with a newer pump with so many parts??? Let’s keep it simple and effective, unfortunately this pump is not it.
The body and design of this pump is the same style as the Zomee Fit and original Elvie, with the exception of the number of pieces. If it were a competition the M9 would win for the mobile pump with the most parts. This design is not my favorite, at all, never has been. I prefer to be able to look down into my bra and easily see how much milk I have expressed. Am I hardly filling the cup? ie, is there something wrong or am I about to overflow my cups? ie, there is about to be something wrong. This design, motor over container, is the only design we have seen that allows a sensor to be used. The sensor that is incorporated into this design should help notify the user when they cups are full or hit the designated volume set (Zomee Fit). Unfortunately for me, none of the sensors on any of the above pumps have ever preformed well and leave me disappointed or overflowing and wanting to go back to an old school cup design. I'm also convinced this design is, in fact, not leak-proof, which I'll get into soon.
Overall, mechanically speaking, they’re not painful. I know, shocking. This pump has three modes: let down, expression and mixed. Honestly, all preform as expected and remove milk just fine. Even with all of my bloody sessions, there’s always been milk. I respond really well to this pump, I cannot complain about output or initial feel. It’s not until after I near a full pump session of thirty minutes that I begin to feel the discomfort of these hard flanges. It’s really strange because even with the blood, I’m not in noticeable pain right away. I don’t think there’s anything around the fact that the materials used to construct these flanges are just a very poor choice. Even if you’re a plastic flange user I would still advise against.
Now for the cherry on the top, leaking. This experience has become an expected outcome, I have not had one session that didn’t result in leaking. I’ve had them leak while sitting vertically at my kitchen table, to walking into my front door from driving home while using my M9 pump. It hasn’t mattered if the cups were full or half full, somehow, some way, they have leaked. When I’ve shared this minor detail with the bemybreastfriend Instagram community the amount of moms whom also experienced this has been overwhelming. They seem to leak for everyone, not just me- I’ll admit, there’s times I wonder if I did something wrong during assembly.
*I want to add my latest experience as of January 4th 2025, I used the M9 with cushions while visiting my sister. The cushions were suggested by a few members of the bemybreastfriend community, have you tried the M9 with cushions to stop the bleeding? With this request, I couldn't leave you all hanging without an answer! I will admit, this worked very well, similar to the M6 with cushions. I was able to pump for the entire 30 minutes without any discomfort at all! The cushions I used did not block the suction port, I had full suction for the entire time and decent output- not the best but decent! However and a big however, they still leaked and they weren't even full. I really wanted to get to the bottom of the why, so I started to break down the cups following this semi successful session. These are my thoughts:
1/4/2025 successful session with cushions
Following this session I carefully disassembled the pump and my thoughts shifted from what I thought was the problem to what I know believe is the actual culprit.
Last but not least, the tech. The M9 is the only model breast pump in the Momcozy line up that is Bluetooth compatible. You’re able to easily control both pumps individually or sync them together. Another pretty neat option is the ability to create your own customized program. They also offer two additional modes to choose from: Milk Boost and Milk Relief. Similarly to the Eufy review, I mention if Bluetooth tech isn’t your thing, then these pumps won’t be on your preferred list either.
Ultimately, they’re not the worst pumps when it comes to effectiveness. But they are the worst in my book as far as guaranteed leaking and potential blood draw.
I’m not going to say don’t buy them but I’m going to say, consider yourself warned. I personally have no plans of ever using these pumps again.
