Amazing pump — comfortable, quiet, and super convenient!
I’m absolutely loving my Momcozy M5 Hands-Free Wearable Breast Pump. It’s so comfortable, discreet, and really lets me move around while pumping — something I couldn’t do with other pumps. I really like the double-sealed design, it feels more hygienic and prevents any leaks.The suction is gentle but strong enough to empty my breasts efficiently, and I love that it has several levels to choose from. It’s also lightweight and very quiet, so I can use it anywhere without feeling uncomfortable. The battery lasts through several sessions and recharges quickly.The design is stylish, easy to clean, and comes with different flange sizes for the perfect fit. Since I started using it, I’ve noticed my milk supply has improved because I can pump more often without feeling stuck to a wall outlet.I totally recommend this pump to any mom looking for something practical, comfortable, and efficient.

Better than the Elvie Stride pumps!!
These pumps are amazing! I originally purchased the Elvie Stride pumps and they just did not have a great enough suction and was not able to get a good amount pumped out of me. I returned those and ordered these in hopes they would work better, and they have been amazing!! I get just as much if not more out of these portable pumps as I do with my wall Spectra. They are easy to put together and take apart for cleaning. They fit nicely in my bra. And lastly they come with a nice little case, which will be so nice for when I go back to work. I highly recommend these pumps especially if you’re looking for a good portable pump option, I have being stuck to the wall🙃
Excelente no dudes en comprarlo sin duda lo recomiendo 🫶🏻🫶🏻 –
Vale la pena comprarlo!
Muy bueno estoy empezando a extraerme y sale bien la batería dura estoy usando el primer nivel y no me lastima es muy bueno me gusta porque puedo estar haciendo otras cosas y al mismo tiempo extraerme es muy bueno la verdad vale la pena comprarlo, lo dude mucho porque veía muchas reseñas malas pero me animé y si vale la pena y además que lo puedo llevar a cualquier lado sin necesidad de estarlo conectando ala luz ….

Worth it!
Would totally recommend. I use this as my secondary pump, and it works almost as good as my Spectra pump. Totally worth not having to be attached to a wall. I can actually get things done around the house and still hold my baby while pumping. Super easy to assemble, not too many parts to clean and it is pretty comfortable. If you’re thinking about getting it, I say do it! I love that it also has a case…Simple pump, but gets the job done. Works just as good as my more expensive wearable.

Must-have for any exclusively pumping mama
I had been on the fence for a long time about getting a wearable, but I’m so glad I pulled the trigger on the M5! It’s SO CONVENIENT to be able to pump on the go and way easier to take care of baby not being hooked up to my Spectra. My supply hasn’t dipped at all, it’s actually gone up because I’m sticking to my schedule so much better with these!My only complaints are that it will absolutely leak all over you if it’s not assembled perfectly correctly (so pay close attention) and it’s not as quiet as I’d hoped…. But you can’t beat the convenience and the price point.

Helps in alot more ways then just hands free pumping
So far my wife loves this thing. It helps so much, she uses it I can’t even tell you how many times a day, so much so that I had to order more parts for it. Just so we could wash a set of collector s and all their parts, and still have a set ready to go.We have two under two, and I have a month of from work to help with the transition.And id recommend these things to anyone.I know insurance and all that will give you free pumps, but I’m tell you as a dad trying to help with new baby stress. The $200 is worth it.

Baby pump
I wish someone would’ve told me how nice it was to have one of these before ordering multiple different flange sizes to try to figure out which one works best for me

Comfortable
It’s comfortable and has different options on nipple size. Different pumping options, sizes, easy to clean. Long battery life. Note: don’t lay down when using them.

Comes with one, so order two. Wish my momcozy just came with this size..I wasn’t stoked that I had to order these separate but they do the job!

I received a product that was clearly used. in a dirty bag inside that was not the original. I know momcozy products and this is not the presentation they come with

Me encanta el sacaleches y la brida funcionaba perfectamente pero es la segunda que compro (27 mm) que al momento de esterilizar (con todo el cuidado) se abomba el plástico 😤 y deja de funcionar porque en la primera ocasión la puse en una extracción y dañó el motor porque ya no sellaba correctamente. No me ha pasado con las bridas originales del sacaleches (24 mm)

1) Why would you make consumers buy a whole separate product (correction: 2 products since they are sold individually) and not just have this be the default size with a 24mm flange insert. Hate being taken advantage of, esp for something I can’t change.2) the flange seems to be looser around the seal of the solid cup, and often comes off around the pouring spout. Pretty sketched out that this will result in leaks and that the flange wont last very long as a whole.
