Do not do it
I would not recommend this pump. Pieces constantly break and need replacing. Milk containers crack easily. Duckbills are hard to twist off/on. Heavy on the chest and constantly slip around no matter how secure your bra may be. Easy to leak. Don’t do it if you want an easy pump experience.

Worked well but pump parts broke constantly and spent a fortune replacing them. My eufy pumps the same or more milk.

I’d give 10 stars if I could
This is the best pump! Granted I’ve never tried any others, but I haven’t needed to! I added this to my registry before my son was born (first time mom) and I’ve had 0 complaints. It’s easy to use and get set up, and I love the app as well. Customer service was amazing in sending me a replacement when I needed one. I really like the wide variety in flange sizes that COME WITH the pump!! As a small sized girlie, I really appreciate that I didn’t have to order a different size separately. It…

My only pumps
I had to replace one about 4 months PP, but other than that these pumps have been wonderful and comfortable for me as a first time mom that ended up 8 months in exclusively pumping due to my baby not wanting the boob anymore (I always was breastfeeding and pumping since he was born, I overproduced for a couple months). So glad to have decided on these pumps! I wear them at home, in the car, anywhere. Very convenient.

This is the best pump! I’ve switched to solely using it even when not needing hands free time. It pulls milk effectively and leaves me feeling very comfortable. It also is easy to clean and store. Highly recommend

Life changing
As a new mom and EBF I wanted a pump that was easy to clean and use. I originally had a different pump that was plugged into the wall and as well as it worked I needed something to use "on the go". I am very satisfied with this product, it is simple to put together and with the momcozy app you can program it OR use the buttons on top. Only "downside" is the writing for the ounces faces the flange so you cannot see how much you've pumped until you take it apart.

Good but Parts Break
I love this pump! It is quiet, semi discreet (I mean it looks like you got a boob job but that’s all), and is comfortable. The app feature is also very nice, as it allows you to turn on the settings and then move on to what you are doing. And, if a setting isn’t what you need, you can create a new one, or change it as you see fit. I really do like it! HOWEVER, there are a couple cons. First, the flange tabs snap off easily. In the 5 months I’ve had it, I think 6 flanges have broken. And the pump…

customer service
Pump worked wonderful! then I started to have a suction/pump issue. Customer Support was amazing, quick to reply and helped me test/trouble shooting some things first and then when it was unsuccessful they helped me with a new pump. I am so pleased with this pump. Comfortable, quiet, easy to use, and easy to get things done well wearing it!

MomCozy Pump Review
Received one side not working to then be followed by the other side to stop working also despite troubleshooting attempts. I was frustrated because I had no other backup to pump for my newborn.
