eufy Security Heated Wearable Breast Pump S1 Pro, Slim Hands-Free with Industry-Leading HeatFlow Tech, Wireless Charging Case, App-Controlled OptiRhythm, Hospital-Grade Suction, in-Bra Use

I love these pumps! I did a lot of research on which wearables I wanted to invest in and I’m so happy I went with these. I will suggest waiting for your milk supply to regulate a bit before you use these often, so you know you’re getting your full outputand you can learn which settings work best for you. They’re extremely comfortable and work well on my elastic nips. With a good supportive nursing bra I feel like I can take on the world while wearing these! I’m able to get tasks done, wrestle my toddler and pump on the go! I even used these on a family trip to the zoo and they were such a lifesaver. Also it is so satisfying when you fill up an egg completely lol I love it!!! They’re beautiful pumps and they help me so much when I can’t always be at my wall pump. Love love love them. They give me the same output as my wall pump. My only issue I’ve ever had with them is I have to keep an eye on how much I’m pumping so they don’t overfill. I wish there was a type of sensor for that on the app but I love them. The app works great and I love the heat settings!

I Absolutely love these wearables! At first I couldn’t get out much milk until I found the right flanges. Eufy provides three different sizes. I bought an off brand thinking I needed a smaller size (15s) but when that didn’t work (barely any milk) I tried the 17s provided by eufy and they worked great. My husband was doing his own research for flanges for this pump and he came across the brand “legendairy milk” I tried those inserts and I loved them even more! Now I get more output than my spectra! They are comfortable. The app is so easy to use. The app was down one day but the buttons on it are also super easy to navigate! The warmth is a bonus, especially in the winter! The charging case is small and easy to pack. It has a hard shell making it nice and durable! I would highly recommend buying when it goes on sale. A friend said she was able to get her spectra and this covered through insurance. It’s worth a try!

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.

This pump is definitely worth the money! I’ll start with why i gave 4 stars. Not that anything is wrong with the pump itself, but the pump only holds 5oz at a time, 6 if you go past the full marking. Not that it’s a bad thing especially because i wanted a less bulky pump than before, i just didn’t catch that it only holds 5 oz 🤷‍♀️. Second, the app is supposed to be able to sync the pumps so they go at the same time but there is a noticeable delay but it doesn’t bother me that much. Lastly, this is may just be me, it took me a minute to figure out how to take the battery off, I feel like it’s a little bit difficult at first. I also am not a fan of the charger because it’s a random magnetic one, i feel like a universal type c charger would’ve been more convenient. Now the good! I love that it’s not incredibly loud or bulky! It fits under my shirt and doesn’t make me feel like i look HUGE. The heating is also so so nice, i really do feel like it does help increase how much I am able to pump. The app is nice too, I don’t really use it, but for ppl who want to keep track of their supply or customize the pump rhythm, it’s perfect. The battery also lasts a good amount of time as well. I pump 2x a day 4 days a week, in the morning and at work for anywhere from 10-25 minutes and i don’t need to charge it until after the 4th day is over. Also, the bag they provide with the pump is cute and easy to clean. All in all, get this pump!!

Updated: 12/25/25 This is my new favorite pump! I reach for it just as much as my Baby Buddha around a month after purchase. I’ve loved using it during MOTN feeds, as I can get my overnight pump in without waking her up. I’ve also used it at work regularly, because I can keep my office door open and attend meetings. I have to keep my office door closed when I use my Baby Buddha, which forces me to keep my office door closed 60-90 minutes per day to pump. I work in an environment that gets regular foot traffic, so being able to keep my door open is a bonus! My Baby Buddha pump is my go to if I am engorged or need to be 100% sure I am empty, or I have the time and privacy to use it. This pump is my go to on my commute into and home from work, and discreet pumping overnight or in public. The suction is great, the speed settings are great, and it does a pretty good job of emptying me. I am so glad I purchased this pump! ——————— I’ve only had this pump half a week and used it over a dozen times, but I absolutely love it! I have continually reached for it over my Baby Buddha motor pump. Pros: - It has a heating feature which can help with expression. - Very easy to change suction and speed settings for your comfort. Even when I am using higher suction and speed settings, the pump is super comfortable and is never painful. - I found the pump very easy to assemble and disassemble. There wasn’t much of a learning curve, and there are only pump four parts involved in assembly, two of which take a fraction of a section to install (diaphragm and duckbill valve). - The app comes with pre-made rhythms. I love the “max output” and “natural” rhythms and get the best output with them. - I have great output comparable to when I use my Baby Buddha motor pump. - The silicone flanges are very comfy. I’ve had no difficulties aligning everything and getting a solid seal. - I can lift my arms and move normally without worrying about breaking the seal. It has made caring for my infant and pumping on a schedule to be very easy. I can easily hold my baby and pump without worrying about dislodging my seal. - The pump is VERY quiet and the pumps are not too large that it’s distracting. I wore it at a public event recently. The event noise easily drowned out the pump sounds, and the pumps didn’t look unrealistically bulky under my shirt. - The charging case gets you a few charges on the go. - All parts can be dried and sterilized in my Baby Brezza dryer/sterilizer. —— Cons: - I have spilled milk a few times, because you need to make sure there is a tight seal with the collection cup and flange when pouring. It helps to have the flange side pointed up to prevent leaks. - The pump can’t be plugged in while using, so if it’s dead, you need to wait for it to charge. A full charge takes a little less than 2 hours. - Replacement parts are a bit more expensive. I just bought an extra pair of collection cups, a pair of flanges, and a pair of diaphragms to have on hand and spent $72 through the Eufy website (with a coupon, original total was around $109). - Quiet, but not silent. Can definitely hear it in lower volume settings. But, it’s not so loud that it is horrendously distracting. - The heat feature will drain your battery faster. I was still able to get multiple pumps off one charge. But if you depend on the heat setting to get much better output, you need to account for more frequent charging. I don’t think you could get a day of consistent pumping with heat out of one charge, if you pumped for 20-30min at a time. —— I am so happy with my purchase. I weighed the pros and cons of multiple wearables, and landed on Eufy. I love my Baby Buddha, but the standard flanges don’t allow for freely moving in public, don’t allow for my to easily hold and care my infant, don’t align with a consistent pumping schedule as a working mom, and don’t allow me to pump at work with my door open. This pump has been a game changer and allowed me much more freedom. Before it was very difficult for me to pump regularly day and night with the Baby Buddha flanges. Now I can throw this wearable on and live life as usual, which has made it easier for me to consistently stick to a pumping schedule. My pumping output has nearly doubled in half a week due to this. I will definitely be able to keep up my goal of pumping 6-8 times per day, thanks to this pump. I’ll update this review if anything changes in the coming months. But I have been extremely happy so far!

I purchased this after hearing many good things about it. I work in healthcare 80+ hours a week and need to be able to pump on the go while seeing patients. Ultimately this pump is a total failure for that, although it does work and I get good output. Pros/Cons Pros 1. Good output 2. Heat function 3. Rechargeable battery pack 4. Remote app functionality CONS 1. Easily spills milk if moving around even slightly at 2 oz collected or more. Cant even walk without spilling milk, the most I can do is the dishes 2. Very finicky pieces. If the duck bill is not securely attached just right the milk does not collect 3. App doesn’t tell you how much milk youve collected and pump will continue until milk is running over. Huge design flaw as it’s meant to be worn under a shirt and cannot be checking output every few minutes, also difficult to see amount in collection cups due to location amd fogging in clear containers 4. Extremely expensive replacement parts and does need replacement every month on the dot 5. Loud motor 6. Painful without special inserts and a lot of practice- I use Legendairy Inserts and they help a lot but it is an additional purchase 7. Cant do fridge method with charging case- will get container gross so I end up carrying both the charging container and a separate bag to carry my detachable parts in. Very bulky 8. This one really bothers me, but they look HUGE when worn. I am not particularly shy with my body but these are embarrassingly obscene to wear even under baggy sweater shirt. It is incredibly obvious. The control lights also sometimes glow through my shirt. 9. Longer to empty me than my spectra. Spectra - 8-12 minutes. Eufy- 30 minutes. 10. Steep learning curve for use. The initial set is not intuitive and the pump was painful until I optimized it scouring Reddit threads and purchasing varying flange inserts. 11. Time consuming to take apart and put together, needs to be exactly snapped right to work. Between the loud motor, many times needed to check if milk is collecting/not spilling over, inability to move with even moderate functionality, extreme cost, finicky parts that fail easily and are time consuming to put together and troubleshoot and very obvious pump I would not purchase this again. I would not use it to wear to work either. It is not discreet and more time consuming to use than a spectra. The only thing I can see these being used for is around family and when sitting perfectly still, such as a long car ride. If you have the ability to pump in an office and do not have to move, with long pump sessions, these may work for you. Edit I have continued using these at work and wear them with a momcozy sports bra which helps the ability to move around. I do still leak from the top if I walk normally with more than 2 oz collected. The heat function has been nice on my nipples, in the cold operating rooms I get vasospasm and they help prevent it. If I store my pump sideways milk will collect into the motor. This happened with my right motor and the output is slightly less from that one. This is after a month of heavy daily use so far as it is my primary pump. I did try the eufy brand spillguards while wearing and unfortunately drops output quite a bit because air cant escape out of the top so milk cant enter the chamber, especially with a good seal with the legendairy inserts.

EDIT: I’m 8 months PP and quite honestly this pump is the one I always reach for now. There’s the diff pumps I have where I use them depending on the setting/place we’re attending but I usually almost always reach out for this pump now. It empties me as much as the spectra (gold model) since my body is used to them now. I think it took at least a few weeks for it to switch since I started to use it way more than the spectra once I worked because they were wearable. I was very surprised! I really had to trust that it was just going to work, it even says that in their instructions you have to just be patient with it. The gentle mode worked for me with the heat - I had to play with the settings BUT now there’s a feature where other people can share their sequence and other settings that you can upload to your app to see if it helps out more. I wouldn’t be able to use them without the legendary inserts though, they are godsend (eufy please make something like this!). I really like the legendary inserts because it’s rubber and the circumferential length of the inserts covers a good amount of surface area to attach to your breast - the pumps really stay in place in my pumping bra since I move all around at work. I also got the plugs for the top so the milk doesn’t go everywhere. I have 4 sets of these so I can use them daily and I started to do the fridge hack at work since it was the easiest for me to do. I believe now they come in a 21mm size too, so I’m really excited to try those flanges too! Also definitely invest in a bottle washer to clean them makes it even more easier to use, I can’t live (mentally) without the Momcozy bottle washer for cleaning them. They clean them soooooo well and I can put two sets of these pump containers in it to clean each time. I hope it’ll work out for anyone taking a chance on these!! Oh also AMAZING CUSTOMER SERVICE!!! I had something I needed from customer service and they were very helpful and attentive and replied very quickly each time I messaged them. That is very rare. Thanks so much!!!! ——————————————————————- LONG REVIEW - Because I feel like with any pump on the market considering how much they cost, they should all have one. I would’ve liked a thorough review compared to most of the other reviews I’ve seen here with all the pros and cons. Or maybe they were just that frustrated they didn’t post here. I was really excited to get this pump as I had been looking really extensively for the past month on what portable breast pump to get. I bought a main plug in pump and was paying out of pocket for this one for work and wanted to make sure it did everything I needed it to do. I’m a health professional and needed something that would empty me fairly quickly and not give me clogs unlike my previous portable one had three years ago. Figured portable pumps have come a long way since then. I also wanted something not as circular so it wasn’t as bulky in my pumping bra as I have to move around a lot for my profession. Most reviews here raved on how my loved their Eufy, even on Reddit so I bit the bullet and bought this. I was in between these, the Elvies and the Momcozys. I even bought Momcozys but returned it unopened since I was convinced these would work better because of the warming feature and the ability to buy more supplies to save even a few minutes during work so I was quicker with pumping. The pumps came earlier than expected so I was excited to have them before I started working so I can to play with the settings and see what mode would work better for me. On my spectra and baby Buddha I get 8-10oz in the morning when I pump exclusively. Or if I feed baby first and then pump I still get 4-5oz left. There are three modes so far I’ve done the max output and the gentle mode. These were the modes recommended by reviewers. When they didn’t work, I tried the others. The output was the same if not worse. I usually get the most on mornings so I pumped each morning to see if there’s any improvement with the tweaks I’ve used. I make sure everything is in place and nipples are centered and I have a tight fit in my bra. First time I pumped I did 20min max output - I got in total 1.5oz Second time I pumped with flange inserts 20min gentle mode - I got a little less than 2oz Third time I pumped with flange inserts and 30 minutes gentle mode - I thought I was doing ok during it (you can’t see milk output unless you pause and fully take it out) - once again I got 1.5 oz It was so upsetting the third time that I put the spectra on right after since I still felt full (despite the recommendation of 30min pumping otherwise you risk nipple/tissue damage), and in 10minutes it gave me 4oz. And each time despite all the borders of container is sealed, it still somehow managed to leak milk out when pouring it into my storage container. For the amount of money this pump can be especially with paying out of pocket for this, it is not worth it. All it has it that it’s pretty and has looks. These are unusable at my work. It would risk me getting a lower milk supply, clogs, and/or mastitis. Now I have to figure out how I’m going to buy another portable again for work, it’s disappointing. By recommendation from users on facebook and Reddit bought the legendary flange inserts. I’ll update this if it improves. But for now stay away from them unless you want to buy something that just sits there useless.

I got this pump after seeing others rave about it online. I have the momcozy m9 and the Spectra S1 but mainly use the portable pump for sanity purposes and not wanting to be stuck to tubes. My m9 motor stopped working and I while waiting for a new one from customer support, I really needed another hands free pump asap so decided to get another one. I was between the Willow 360 and this pump but ultimately decided to go with the eufy S1 for the warming feature since I use the fridge hack and HATE having to either put on the flanges cold or wait for them to warm up. Let me tell you, the warming function is a game changer. I think it’s also helped with my output. I’m not a big supplier so every ounce counts. I also love that the machine doesn’t automatically start pumping when turning it on. You have to press the power button one more time to get it started. This is important for me because I like to start at a lower setting and gradually build up. The pumps usually save your previous settings so if I’m at a really high setting to end and don’t adjust it, then my next session starts out painful. I didn’t think I would care about this, but I love the charging case! I don’t have to have all of these cables on my nightstand anymore and it’s good to have traveling. Plus, I feel like the charge doesn’t last as long as advertised (mine only lasted about a day), but that might be because I use the warming feature so frequently and sometimes forget to turn the pump off after a session. I love that it converts between oz and mls. Something small but it’s a nice touch. There are some issues that I don’t like. For me, these are minor issues and just more annoying. I would get the pump again just for the warming feature alone. -The major annoyance is that when I sync the pumps on the app, it’ll start off at the same rhythm but for some reason starts to go off as time progresses. Also, I’ll frequently have one still in simulation while the other one has moved on to express mode but that doesn’t make sense why it would do that since they SHOULD be doing the same thing. It’ll show on the app that my right pump has progressed a lot farther than the left side even though the time is the same. I thought maybe it’s an app glitch but even if you don’t sync it and you manually start it on the pump itself, it still has the same issue. The only way I’ve gotten around the rhythm issue is by manually changing between expression and stimulation. -There’s no timer on the actual pump. You have to rely on the app in order to know how long you’ve been pumping. -The pump itself easily tips over and the milk spout is right next to the charging port and the buttons so it may get damaged over time if you’re not careful. -The measurement on the cups are off. It’ll say like 0.5oz but when I actually measure it out into my Medela storage containers, it’ll be more like 1-1.5 oz. -When your session is done, you can type out the amount of milk as exact amounts, but if you type it in later or have to edit the amount, then you can only scroll in increments ( for oz it’s by 0.3’s and for mls it’s by 5’s). I’ve only been using this pump for two days but it’s my favorite pump so far. I’m probably going to use this as my main pump. :) Edit: Removing a star for case design. I do like the pump, but finally went out this week and realized you can’t put the pump inside the case without removing the protective flange cover because there’s a bump in the middle… what’s the point of having a flange cover if you can’t use it at all times?
