eufy Original Milk Container (2-Pack) for Wearable Breast Pump S1/S1 Pro, BPA-Free Reusable Breast Pump Container Collects Up to 5 oz (150 ml) Each

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.

Updated: 12/25/25This 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!

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 1.5ozSecond time I pumped with flange inserts 20min gentle mode - I got a little less than 2ozThird 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 ozIt 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 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/ConsPros1. Good output2. Heat function3. Rechargeable battery pack4. Remote app functionalityCONS1. 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 dishes2. Very finicky pieces. If the duck bill is not securely attached just right the milk does not collect3. 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 containers4. Extremely expensive replacement parts and does need replacement every month on the dot5. Loud motor6. Painful without special inserts and a lot of practice- I use Legendairy Inserts and they help a lot but it is an additional purchase7. 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 bulky8. 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.EditI 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.

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.
