Size: Heated S1 Pro with Charging Case
I love my eufy pump! I'll start with i also have the baby buddha2.0 and I also had another wall pump but returned it due to lack of use. Powerful, wearable breast pump that's a game changer! I love the heating feature and I'm convinced that the yield is higher when I use heat. They are also extremely comfortable, well made- I love the material they're made out of- thick silicone. Not flimsy stuff that will eventually degrade. The pump also comes with 3 sets of duck valves which is nice, and the diaphragms are super well made and thicker material than I've seen for any other pump. I've been using these pumps every day now for 3 months and they still work perfectly. Again, I LOVE them. The most I've pumped seems to be around 170 when I fall asleep wearing them at night and do not empty them half way through my pumping session. These pumps are super easy to clean as well. As long as these bad boys keep working- i rate them 10/10. Side note, I've never had leakage and I always have a great seal between my breast and the pump (and I have rather small teetaws). I find it to be totally worth the money, only breast pump I'll use. Just soooooo convenient! Also, can run through 3 full pump sessions before I have to charge!

Size: Heated S1 Pro with Charging Case
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!

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.
