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.

Do not buy! Look elsewhere!
This is my second replacement pump and I’m having trouble with it again! My first pump only lasted 1 month due to the motor quit working and now my replacement pump won’t charge after 1 month! Two thumbs down for Momcozy…

Don’t recommend
One of the motors lost battery really fast so Babylist sent me a new one. Now one of the motors is going bad and started seeing a dip in my supply so I started using my Spectra and brought my supply back to normal. The app doesn’t connect every once in a while. I’ve only been using these for 6 months only while I’m at work. I will never buy Momcozy pumps again.

Absolutely love
This has been my absolute favorite pump by far. I love the app settings, you can customize your own rhythm or use preset ones. Great suction, so comfortable, ans easy to use.

Worst company
The pump is actually decent but the tech is nonexistent. My app gave out on me more than once in the 5 weeks I used this item.
I reached out to Momcozy to troubleshoot shoot and they had absolutely no answers. If you are looking for the pattern customization they offer don’t bank on Momcozy

My preferred pump despite the flanges breaking frequently
I have 7 pumps and this is my current favorite.
It works pretty well. I like that they have a left/right switch so I know which pump has my settings for each side. If you're busty it is NOT subtle at all, but I don't exactly walk around doing errands in public while pumping so whatever. I've had no issues with storage or leakage. It has great suction so I don't feel like I have to use my Spectra anymore. It's also probably the easiest of my pumps to clean, with no super small parts that…

Strong suction and very comfortable. I was pumping with a pump that wasn’t hands free but after getting my M9 I’m producing way more! The suction feels natural but also strong! You can manage settings from the pump itself or on the app. Love that the app tracks how much you pump each day. The one time I had trouble with the app, I emailed customer support, they emailed me back the same day and solved my problem. Excellent customer service! I give five stars all the way!

Easy to use!
My main pump is the momcozy v1 pro so I got this to use when I went back to work. It is easy, quiet and does a good job emptying me out

Pump is working great. Wife is very happy with this purchase. More over customer service is top notch. They support your purchase like no one else. Wife has been using for 6 months now.

Frequent breaks
I had my baby in September and by November both flanges had torn and lost suction. Baby list replaced them then one of my pumps motors gave out in December. Baby list replaced again. Then in January one of the new flanges broke at the prong on the bottoms and one of the collection cups cracked. When I asked for replacement parts this time babylist said it was momcozy’s problem now and to talk to them. I use these multiple times a day at work and it’s very frustrating to not have the replacement…
