Pump is okay. I have much cheaper pumps that give me the same or even better output. The convienice of this pump just isn't there. Too many pieces to undo, while leaking milk everywhere, to get to the milk collection cup to pour out. My other wearable pumps I just detach the motors and pour the milk. Super easy and convenient when you're pumping on the go- like in a car. This momcozy pump makes it difficult to pump on the go, in the car (which I need to do for my job/while working). My first baby I had the momcozy s12 and it was fantastic. Def. Prefer that design over these overpriced, terrible designed pumps. Disappointed I spent money on these. :(

Poor suction, app was a bit pointless. Used this as my portable pump for my third baby/third time breastfeeding and I was not thrilled with it. I’ve tried several other portable pumps and this was the worst output and suction. I’ve heard from friends that other momcozy pumps are way better

Dropped my supply
Dropped my supply. At first I thought it was other factors but I was never able to get my supply back using this pump. Do not recommend despite it’s useful app. Back story- I was using a the medela in style pro and the lansinoh wearable but until the lansinoh stopped turning on. I had previously used it with my first so I guess it was worn out for my second I decided to explore on newer ones with technology and found this upgraded one from a popular M5. My supply dropped drastically to the point I needed to use formula. I started using my medela to try to figure out what was happening and I was able to gain my supply back. Don’t recommend purchasing as other reviews warned of this as well.

would not recommend. i have had these for 3 months and the suction is already lost. the parts break super easy. i’ve had to replace my flanges three times now from breaking, and two of my collection containers rim has broken to where it won’t seal. the app is basically useless other than for creating a personal setting but my pumps won’t reconnect now anyways. the storage containers also leak terrible, and you have VERY limited mobility while pumping. i would however recommend the s9 or12!

Dont bother
This pump was great for only 3 weeks! After the 3rd week it lost suction. I contacted momcozy and they said they can only replace one. After I did that the second pump lost suction 2 days later. They tell you that you have to replace the parts every month ! I’ve spent about 100 dollars already and the replacement pump still hasn’t came. My bay just turned 4 weeks and I’m out of a pump looking for one because I’m waiting on the replacement . Don’t waste your money on something that’s going to break and you need to constantly replace the parts.

Brakes too easy
I purchased this for my daughter, she had this for a month and the flame piece that connects to the duck bill keeps breaking she has had to replace them five times it’s costing so much money for these replacements. They are $25.00 for one!

MomCozy M9 #PumpReview
As a first time mom, I wasn’t sure which breast pump to buy. After reading tons of reviews, I’m thankful to share how much I love my M9 Momcozy Mobile Flow pumps. I use my M9 pumps everywhere I go. Working as an ICU (Intensive Care Unit) nurse, it can be hard for me to step off the unit for a for a formal pump break. My M9 pumps have allowed me to quickly pump to provide nutrition for my baby. As you can see I have quite a collection of back up parts. This is my daily set up when I’m heading into work. One of the best parts of the mobile flow pumps is the ability to easily store milk using the storage lids. The biggest change I’ve noticed since using it is the amount of time I’ve saved at work not having to store milk and clean parts. Having two of the same pumps allows me to keep one at work and one with me on the go! Mamas I highly recommend you pick one up today! #PumpReview

ehh- there's better
great customer care, terrible product. it works half the time, the app is not worth using IF you can get it to connect. love that it has 15 settings, but it's almost too much. the product is difficult to clean, compared to others like my medela, and use on the run as it has to be completely dry and all parts need to be "built" before storing. the design of the "bottle" catches and loses a lot of milk in all the crevices.

Overall a really good pump. I love it now that I don’t have a crazy oversupply. I love that you can customize your settings in the app, and have multiple pump cycles saved. It does have a lot of parts, which makes cleaning and assembly a little annoying, but it’s definitely a good pump to have. It has a ton of different settings, and preset modes in the app, and the collection cups come with little lids to easily store milk in the fridge.

M9 review
#pumpreview The Momcozy M9 was my first pump that I owned. I loved the look of it from the day I received it and the case was amazing as well I was able to fit everything I need inside of it. The pumps flanges are soft when in the skin but have a hard part to them as well. I use mine mostly at work and in the car but lately it has just been at every pump during the day. I get the same output as I do with my Medela but this is way more convenient and comfortable and I can do multiple things at the same time or actually sit and relax in my comfy chair vs the folding chair I have by my wall pump. Overall the biggest thing this pump did for me was make it so that pumping wasn’t horrible and it made me not want to give up as I was able to pump on the go and wherever I needed to be. The only hiccup I rant into was the flange attaching to the collection cups. It would keep breaking since then they have upgraded the way the set is made and the last set I bought has actually not broken in a while. The trick is to not pull the flanges and collection cup apart but to twist everything off first the collection cup then the duck valve part off the flange.

Momcozy M9
This pump allows me to travel anywhere I want to I don't need to be plugged into the wall. I get a great level of output and it's really quiet. It's super nice to use when I'm on the go or at work overnight you can hardly even hear it while I'm pumping

Broken within a month
It's been a month since I started pumping once or twice a day and it's already broken. I'm very disappointed. I've read that it's common on the M9. Buyers beware.

Always breaking
The concept of this breast pump is great in theory, however the flanges constantly break. It takes a while to get the replacements making the pump useless.

Convenient but shifty
BF mom of 4 children total. This pump is cute, convenient, and costly. Mostly, it works great. It’s super discreet and functional. I hate the bluetooth part of it. I have never connected it and probably wont. Actually after using this I feel weird pulses on my breast which makes me think it’s radiation from the bluetooth. I don’t need that extra damaging stuff. I am researching a similar pump WITHOUT that. Sometimes this pump is a beast and other times it frustrates me so bad! Especially when I am pumping from work and have limited space and time. The top is always hard to come off, milk spills soo much! I actually cried a few times. Other than the limited functions, leaks, and electrical pulses it’s ok. The price needs to be reduced for the leaking alone! And the difficulty disassembling to pour your milk in the bags!!

After 3 months of loving this item, one of the pump machines stopped working. It will show the battery button when it’s charged but will not turn on.

The worst!
Terrible pumps!! I bought these because I needed to replace one of my Elvie pumps. I figured it was cheaper to buy these 2 than 1 new Elvie and the suction grade was supposed to be better. I can't even get more than 1.5oz on the highest setting. My Elvie's give me 3-4oz on a medium setting in the same timeframe. I do NOT recommend these.
