Game Changer
I absolutely love this pump. For my first child, I had the plug-in Medela and the Elvie which I absolutely hated. I still have them but haven't touched them since I bought this one. I pump exclusively with the Eufy and my milk supply has been great. After the first few times, cleaning and set up is actually pretty simple. I love not being stuck to a wall and being able to do laundry or cook dinner while I pump. Make sure you're using the right size nipple insert. Battery life is great and I can do about 4 pumping sessions before recharging. My only issues with this pump is that pouring out the milk is sometimes difficult and there's no sensor for it to shut off automatically when it's full. I had one experience where it overflowed in my bra.

Not working and took days to get supply back up
Was excited to get this pump but it is inconsistent and first pump I got 7 oz but pumps #2 and #3 barely anything. I took the pump with me to an event and with it not working I ended up in a lot of pain with getting almost nothing 2 pumps in a row. Supply dropped after I could not empty milk 2 sessions in a row. Not sure what is wrong with this pump

Strong pump
It works really well. Much better than the elvie. My one complaint is that it occasionally leaks when pulling it out of my bra.

Love it
[This review was collected as part of a promotion.] This wearable breast pump is a game changer. As you know heat therapy help increase milk flow. Before I have to add the gel pad to the pump for the heat therapy, now with the heat function I don’t need to do it anymore. The suction is strong enough to empty my breast. With the app you can know how much milk you pumping.

Life changing
[This review was collected as part of a promotion.] I absolutely have been loving this breast pump! Not only does it work so well, it makes me feel super bougie! It has so many features that I would have never thought of, but have been so important and helpful to me. The size of the breast pump really does a great job of covering and being able to suction correctly. I also love that it comes with a bag, which makes it so easy to take with me. The features on the breast pump have made it so comfortable for me since it allows for heating and allows me to control it through my phone. I know I already mentioned the portability, but it really is something that is important for me as a working mother since I have to go to work but still pump. I definitely recommend getting this! It has honestly been life changing!

Comfortable pump
[This review was collected as part of a promotion.] When I tell you this pump is SO good I mean it! It’s sooo easy to use and put together. It’s very comfortable and doesn’t hurt my nipples at all! It’s not loud like other pumps out there! I like it because it actually does get all the milk out and I can rely on it to do that! It’s easy to clean as well! It won’t break if it falls and you can just put it in ur purse on the go!!

This wearable pump is awesome! I love how small, c
[This review was collected as part of a promotion.] This wearable pump is awesome! I love how small, compact, and discreet it is. The parts are easy to clean. I got about five ounces on my first pump. Would definitely recommend this pump to anyone who wants the freedom to move around while pumping. App is easy and user friendly, perfect for a new mom. Very quiet too! Great value for your money.

Breastfeeding mamas helper!
[This review was collected as part of a promotion.] I’ve been using the Eufy heated wearable breast pump for a few weeks now, and I’m honestly impressed. It’s very comfortable and convenient, especially when I need to move around or get things done while pumping. The heating feature really makes a difference, it helps with milk flow and makes the whole experience much more comfortable compared to other pumps I’ve tried. The suction is gentle but still effective, and it’s surprisingly quiet, which I really appreciate. The app is also easy to use and helps track sessions and milk output without hassle. If I had to mention one small thing, I’d say it takes a bit of practice to get the positioning just right at first, but once you do, it works perfectly. Overall, it’s been a great addition to my breastfeeding routine, worth the investment for the comfort and freedom it gives!

Heated Pump with too may cons
[This review was collected as part of a promotion.] I really truly wanted to love this pump but it is just not one I will be reaching for in my breastfeeding/pumping journey. The heat feature is really cool and I love that it is incorporated, but overall the pump is too difficult to (1) put together (2) clean (3) place properly and (4) transfer milk out of. For those reasons I am sticking with my Elvie. The battery life is great and it is quiet - all pros.

Great choice and affordable
[This review was collected as part of a promotion.] Going to save this for my next baby but so far it works great this very convenient to have a breast pump that is hands-free and actually has good suction! I feel like the price point is really affordable compared to some other ones as well

Looks perfect
[This review was collected as part of a promotion.] So the portability of this looks very efficient and easy to pack around the fill of it was very soft so I'm guessing that the comfort would be very good but I have an issue I cannot use this product because my doctor has put me on medicine for postpartum and I cannot use this so if you would like me to send it back I can or I could regift it to my oldest daughter because she just found out she is pregnant also, and I would like to put it to use and have it be reviewed and told me and then I can make a new review.

I love this!
[This review was collected as part of a promotion.] Wow! The battery on this is amazing. It is very comfortable and I cannot believe how portable it is. The noise level is very little and it isn’t too loud at all. The suction strength is also amazing. I can honestly say that this is the best pump I’ve ever used!

Not worth the money. Buy a Spectra.
Doesn't work well for me. Flange inserts are crap. Pumping very painful no matter what setting & I was fitted to ensure I was using the correct size. I can't even get one quarter of the amount of breastmilk with these pumps as I do with my Spectra.

Definitely recommend
I actually love them the heating function is amazing. The only thing I will say is that the suction is STRONG so be prepared! If you’re sensitive like me, you may need different inserts (I got some from America from legendariy milk) The heating feature is also Amazing. One star taken off only because I do feel they are heavy compared to other wearables I’ve tried!

Pretty Great!
Love how I can be hands free - the heat is such a nice perk, too. Putting the pumps together is a bit cumbersome but it’s worth it. I think it works just as well as my spectra and I prefer these over it :) totally worth the investment!

Not bad
I was really excited to get these in the mail. Not only did it come with replacement flanges & duckbills, but they’re relatively cheap if you’ve gotta buy more later on. The heating feature is super nice but unfortunately does not help with my let down. It’s really quiet and pretty discreet which I love. However, I’m only getting about 4-5 oz per pumping session total where my Momcozy M5 doubles that almost every time I pump. The suction just isn’t that strong for me and I’m not a fan of the different suction patterns to choose from. Overall, it does do its job by extracting milk but if I use these as my main pump, I’ll 100% see a large dip in my milk supply which I am really trying to avoid.

Nice pump but not for me?
I bought this pump because of his hospital grade suction however I barely get an ounce when pumping even at the max setting and using the different features including the heat. When I use my M5 or spectra I get atleast 3 oz per side. It makes me sad because I really wanted this pump to work for me for when I transition back to work.
