Size: Heated Breast Pump S1
I’ve used the spectra, momcozy S12, ameda glow and now this pump. This one is by far my favorite. Spectra is bulky and we’re taught it’s “the primary pump”. Ignore that! The spectra is bulky and cumbersome. The momcozy is great but is a tad bulky with the motor on top and has no extras to it. The ameda leaks like crazy — drove me nuts! This one draws more and feels better! The heat is amazing, the texture of the cup feels so much better and the app is pretty intuitive. I love the gentle mode. And I love that there is more than one profile to use during the session depending on the desired outcome. Seriously, best pump! And it doesn’t leak! That’s my favorite part. Great output, feels great, no leaks, quiet, and high quality!

I can’t praise this pump enough. It has strong suction, it is comfortable, it is easy to clean, its parts seem like good quality, there are multiple flange sizing options, it is pretty quiet, it keeps a charge really well, it is extremely portable, the app is so helpful and user friendly with lots of combinations to customize your pumping session, and the heating feature is great for someone with slow milk flow. I have consistently pumped around 2 more ounces than with my old pump.

I apologize in advance for this long review! Also for my grammar/typos…. I’ve had this pump for two days so this review is obviously only based off two days of use. I exclusively pump. I have a 3 month old and a 3 year old so I’m constantly moving. I needed a wearable comfortable pump. This is my second wearable pump the first one was cheap and got the job done for the most part but it only had two modes. I have been researching other wearable pumps and these wearable pumps are an investment. I bought the Eufy on prime day which was an amazing deal. I was sold on the Eufy because of the heat setting. I’m very sensitive like I have to have the suction low but I’m also an over producer. Anywho I love this pump!! There is an app to connect it to your phone and you can control it from there or the pump itself. You can sync both of them or have separate modes. You can have an auto shut off! Whatever setting you leave off on will be the one that is suggested when you turn it back on. Also in the app you can track your ounces you do have to manually put them in which isn’t bad. I absolutely love the heat setting it’s very comfortable and you can have it automatically shut off on a timer too, I’m a hot person and this doesn’t add to it or make pumping unbearable. Now moving on to putting it together and taking it apart. Once you get the hang of it man it’s super easy! I haven’t spilt any of my milk while taking it apart which I’m thankful for because we all know it’s hard work making it anyways we don’t want to waste it! So I take my fingers and pull by the spout in the opposite direction from the motor. Someone pulling them in two different directions at the same to get the magnet to come apart once I fill that it’s not connected anyone I pull the motor off. I’m sure I’m not explaining it correctly but once you get it down it’s so easy! The other parts are super easy to take off and put back on, also very easy to clean all parts. Now I’ve noticed when putting the flange back on the milk container easier to push the sensor in place and then push the center of the flange where your nipple goes in to place first before doing the rim. Just somethings I’ve found easier for me.! Oh also when pouring your milk always have the flange facing up not down if you do you’ll lose some milk! I’ve caught myself trying to do it that way and then I remember! When I say I collect every drop EVERY DROP comes out again you’ll get it down with what works best for you! One last thing the charging cord it’s just one with a split end with TWO chargers on it. Oh I also charged it before my first use. I didn’t charge it at all one day and I pumped 5 times in one day my sessions were 20 minutes a piece. The next day I pumped with it two more session and then I charged it. I felt like it holds a good charge. I’m sure I’m leaving so much out but again it’s amazing!! I’m so sorry that I rambled I hope this helps someone else. **Update 8/30/24 I still love this pump! I use it 3X a day! I absolutely love not being tied down when I’m driving or working! I’ve literally pumped everywhere! Which makes life easier when you are constantly on the go! My family and coworkers don’t even hear it most of the time because the surrounding noise is louder. I don’t have any complaints other than I wish it held more ounces but I can’t even fault them for that.

I liked this pump a lot at first—it’s super convenient being hands-free, and the heated feature felt really nice in the beginning. It worked well for me for the first few weeks and made pumping feel a little more comfortable and efficient. That said, I ended up having some issues with clogged lymphatic fluid, which then led to clogged ducts. After talking with my lactation consultant, I was advised to stop using heat and switch to ice instead, and that made a big difference for me. I also noticed the diaphragm tends to leak—especially if you’re holding it upside down. You have to keep a hand over it so it doesn’t fall out and spill, which isn’t ideal when you’re already multitasking. Overall, I do think it’s a well-designed pump and has some great features, but it just wasn’t the best long-term daily option for my body personally.

I absolutely love this pump! I primarily breastfeed but pump 2x a day and I’ve been using it for 2 weeks and I feel I get such great output with it. Better than when I use flanges and my spectra pump. This is my second child and having wearable pump is so helpful chasing around a little one. The heating function was so nice when my milk came in and I was feeling so engorged. I still use the heat because it feels nice. I do wish the cups held a little more milk because I do tend to max them out but probably because I only pump 2x a day. Also I was loosing a little milk when I would remove the motor and pour it out so I suggest leaving the motor on to pour the milk, reduces where it can spill out of. But I highly recommend this pump!

I saw these on sale and decided to give them a try. I'm so glad I did because these are awesome! I'm a mom of 4 so I stay busy, overproducer that exclusively pumps due to latching issues for baby, and have dmer which causes anxiety during pumping. The heat on these help so much with the dmer that I don't dread pumping everytime plus I have so many more letdowns with it. I respond to these faster than I have any other pump and it's a more comfortable pump than even my spectra which I previously claimed as the best! I get the same amount as with my spectra but even faster which is awesome because I don't have time to be anchored to a wall and most likely couldn't stick with it for a whole year especially around the busy holidays. The suction on these pumps are strong! The highest level I use is a 4 but usually a 3 and the max mode is my favorite! This pump comes with everything you need. I worried the charging cable would be difficult to connect but the magnet is strong so it's really easy to connect them even one handed. I keep heat on for the entire pump maxed out so that drains the battery pretty quick. I generally get a little over an hour and a half out of battery life because of this but I usually just charge them after the second use so they're always ready to go. I use the fridge method (rinse after pumping and refrigerate) and it causes no problems with the heating. It's nice because it warms it up quickly out of the fridge which I'm sure I'll love even more this winter! The things I don't like as well are; The app is great to use controls so I don't have to look down my shirt to change settings if I want but it does bug out sometimes. I clear the app off my phone and it's fine when I open it back up. I wish the heat had the option of turning on for the whole 30 minutes of pump time instead of just 15 minute at a time. It has the plugs you can buy to keep them from leaking if you bend over. I bought them but they still leak as medium-fast droplet so it's never completey leakproof. I have never had issues with it leaking because I'm not bending over that far while pumping so I rarely use them anyways. I do prefer the legendairy milk flange inserts over the ones that come with these but I use these a lot. I wish they had the option to buy the charging case by itself incase after buying the pumps you decide you want it. So far I haven't had much regret over not having the charging case but I may change my mind around the holidays when i'm pumping on the road a lot. I would definitely buy these pumps again if something happened to them because now I couldn't see myself pumping the next 10 months without them I love them so much! I will update if I change my mind about these.

MAMAS. Yes hands down this is the pump. It’s expensive but entirely worth it. I’ve always gotten free pumps through the state my last 3 pregnancies, but I chose to upgrade from my wired Medela swing maxi, and omg such an amazing experience so far to get something this nice. Works amazing, and I’m already pumping an extra oz or 2 since I switched YESTERDAY. has multiple setting for suction and I’m the type that NEEDS a decent amount of suction and it does exactly what I want. The heating effect is also so nice, feels like my boobs are at the spa lol if you’re skeptical don’t be. 10/10 love this pump. Beautiful!

I use these for purpose of portability and ease of use. I love the heating element I feel like it helps with output. I also enjoyed that it came with different flanges. The battery last a long time, and I dont have to frequently charge them. I love that I can put it in dishwasher. The app is easy to use, and I like how it syncs both machines. I would definitely recommend to others that are looking for a hands free pump. My regular pump is spectra s1 and I get the same output from both so it is just as strong.
