Heated Wearable Breast Pump S1 Pro, Slim Hands-Free with Industry-Leading HeatFlow Tech, Wireless Charging Case, App-Controlled OptiRhythm, 300 mmHg Strong Suction, in-Bra Use

I am a nurse on a busy floor, these breast pumps have been a life saver for me. Easy to use, the heating feature really does help with my letdown, easy to clean, and the charging case is a game changer. I can use the pumps multiple times a day without having to recharge the pumps or the case itself. The battery life on the case lasts for a pretty long time. The suction was also strong, which was impressive to me. For wearable pumps, these are a pretty good choice. Way better than momcozys in my opinion. If you’re contemplating whether or not to buy these, yes they are expensive but I would say it’s money well spent. 10/10 would recommend.

This pump is amazing it's been 2 months of use after a failed attempt with a different pump! I normally forget to write reviews but I love it so much! First session I got 5 oz in ~10 mins. I use these probably more fequently than I should since I have a spectra 2, this empties me quicker though. They will help me when going back to work next week for sure, I'm about to order more parts now to help with that transition. They are powerful so play with the setting to help you out the best. The heated feature is nice but I barely use it. Be careful with bending over and you have to watch out for overflow because it happens, make sure you also put the flange together correctly or milk will spill on you. Great design, functionality and fit for a heavier chested person. Love this product and it makes pumping so convenient :) great price also especially if you catch it on sale!

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.

This wearable pump has changed my entire pumping experience. The only reason I can’t give it five stars is because of the occasional leaks. I’ve tried lifting my toddler out of her car seat while wearing them and the seal ca pop. I am also a busty mom and I feel like I needed to use even bigger nursing bras to hold them place. I do think they are great quality. The app makes it easy to customize your pumping experience. The warming feature is a plus, but honestly a cold pump from the fridge just helped me stay awake during nighttime sessions. The charging case is also great to have to keep everything together and store when not in use.

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 originally had an issue with my shipment and had to reorder, but once I finally received these, they've become one of my favorite wearable pumps (until the S2 Pro). The biggest pro is the output. I get excellent milk production with these, and the heating feature is amazing - it really helps with comfort and milk flow. They've been reliable, and I use them regularly. I wouldn't say my supply has severely increased, but they definitely do a great job at maintaining my supply and emptying. There are a few downsides. I find them a little pinchy, even when using flange inserts. They're also more time consuming to clean because of all the small crevices. The included cleaning brush was a nice idea, but it scratched my milk collection cups, and I accidentally tore one of the duckbill valves while cleaning. Replacement parts are also on the expensive side, so that's something to keep in mind. They're not quite as discreet as I had hoped. I personally wouldn't wear them out in public unless I had a sweatshirt or hoodie on, and coworkers on conference calls have mentioned they can hear the motors, so I still use the mother's room at work. Overall, despite the drawbacks, the heating function and strong output make these a wearable pump I'd recommend. Just be prepared for a little extra maintenance and higher replacement part costs.

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 have insufficient glandular tissue and had to combo feed. It was very defeating and frustrating but the eufy helped so much when I went back to work! I was much less stressed about things and could do my job and still pump 3x while at work. Didn't get a full 5 star bc it is louder than they say and it does occasionally not line up and I would feel like it was working only to realize it wasn't on right and I got nothing but that may be user error. There are a lot of nooks and cranies to clean which always made me nervous but I got breastpump wipes which helped a lot. The heated feature is nice and I did really enjoy being able to power pump and change up the settings so much! It's a very customizable experience. I was very pleased.
