Review: Exact replacement, perfect compatibility. - These Eufy milk container replacements are a must-have if you use the Eufy pump. They pair perfectly and fit exactly as they should with no leaks or issues. Having extra containers makes pumping so much more convenient and cuts down on washing throughout the day. Great quality and a perfect replacement. I’m glad I purchased these.
Review: Best pump I've ever owned! Stunning quality! - If you are like me... I've tried breast pump after pump to find one that really works. The other pumps I've tried are elvie stride plus, momcozy m9, momcozy s9 pro-v, medela pump in style, medela hand pump and the momcozy air 1 which has been my main pump for the majority of the last 2 months and comparable to this eufy. So let's talk about it. I have twin babies to feed so every bit of milk is vital! With all my other pumps I felt like quality wasn't there where as the eufy blew me out of the water and actually believe is worth the price tag especially with the charging case. Things that I noticed that is unique about this pump is on stimulation mode it really closely resembles my babies suck instead of a machine like feel which was surprising. Love love love the heat function! The pour is so satisfying! Although make sure to hold the diaphragm when pouring. Which when it comes to design is fantastic compared to the air 1 because I endlessly was pulling apart the entire milk collector to get every scrap and felt really messy after awhile. So the eufy made a flawless design that gets every scrap of milk without the milk mess. Also... I've watched reviews and people said the pump was loud but honestly I think its the quietest pump I own! Total pump and case seem to be of high grade material. I feel totally completely emptied from this pump which is HUGE! I've been getting clogs left and right and spending so much time working them out and hands cramping and then still not feeling completely empty with my other pumps. So when I say this eufy s1 pro is AMAZING... believe me and get this for your first or second pump because I wish I had this one so long ago! Cheifs kiss and 5 stars for the win!

### ⭐⭐⭐⭐⭐ Great pumps/ exclusively pumping
*by B***N on December 2, 2025*

Absolutely love these pumps! I am exclusively pumping so having the right pump is extremely important. When I first started using them I did see a slight decrease in my supply but after messing with the settings for a couple of days my supply came back and even increased a few ounces a day. It’s easy to get frustrated along the process because the last thing you want is a dip in supply but once you get the settings correct for you they are great. I love the heating element on these and they also hold a charge for a long time, the charging case is an extra bonus. The app is very user friendly and helps you figure out what setting you need for the highest milk supply. I have been using these for 4 months now and they are still working great. My two biggest complaints are 1) make sure these are very securely put back together or you will have milk spill all over you. This has happened more times than I like to admit and is so frustrating. Take the extra 5 seconds to make sure everything is completely sealed together. 2) It’s really hard to tell if they are put on correctly and lined up all the way. I try to always check about 5 minutes in to make sure milk is coming out because I have almost crashed out several times after pumping for 20 minutes and then realizing it wasn’t on correctly.
