Confy, easy, silent
It's super quiet, comfy to wear, and the size is just right for walking around. I could move around easily, but some moves might make it slip. I'm giving it 5 stars; it's exactly what I wanted for the price and quality.

Best handless pump
I am a momcozy user for life. I replaced my old M5 with this one and I really like the overall design and function of the handless pumps. It is nice being able to use them at work and move around. Definitely worth the price. The suction isn't bad either. I think it is pretty strong and gets the vast majority of the milk out. If you need to get inside of the pump due to liquid getting inside, there are four small screws under the rubber flaps on the motor part. It is easy to unscrew to let dry out before tossing the pump doe to an error.

Essential Tool for Comfortable and Efficient Pumping
A must-have tool for pumping moms! This product makes it incredibly easy to find the right flange size for your breast pump, ensuring a more comfortable and efficient pumping experience. The measurements are accurate and straightforward, eliminating all the guesswork that often comes with figuring out the correct fit. Using the wrong flange size can reduce milk output and cause unnecessary discomfort, but this tool solves that problem effortlessly. I highly recommend it to any mom who wants to maximize the effectiveness of their pump and make the entire process smoother. It’s a simple yet essential tool that every breastfeeding mom should consider!

Love and hate situation
Okay first and foremost I do want to say that I love this pump it’s so convenient especially with all the wires , it’s exhausting just sitting there , I do it with my first born and it was not it , it actually made me stop breastfeeding at 3 months when I wished I would’ve done more but I do want to say I rate it 4 stars because I wish they would change the fact where the milk comes out from . Its super annoying when I’m trying to put my pump down to get my bag ready and it leaks or even if I have them on and im cleaning if I bend over a little too much I will spill everything on my shirt and bra because it will come out I can say that’s my only pet peeve with this pump I have found that so annoying . I have posted a picture so you can get an idea of where the hold is at and how easy it is to spill

Just buy it
I’m tired of using a manual breast pump, and this one is a real find for me. I can walk around the house and do my own things while it’s working. I’ve also noticed that I’m producing more milk, which makes me very happy. Thank you, Momcozy.

Great Item, Ended Up Not Needing It
My friend had this and let me borrow it when I started breastfeeding. It helped me to accurately find my flange size which was so beneficial in having a more painless experience and saved me a lot of time and money. I ended up purchasing one of my own to have on hand so I could continue to measure as my body changed, but ended up switching to exclusively doing formula and never used it. Because of this I ended up returning it, but I would highly recommend to anyone who does need something like this!. It's accurate, and easy to use!

Just what I needed ♥️
Decided to buy extra attachments so I wasn’t having to constantly wash the pump parts like I was and this was the best decision I made!
