### ⭐⭐⭐⭐⭐ Easy to lose

### ⭐⭐⭐⭐⭐ Best pump I've ever owned! Stunning quality!
*by H***N on July 29, 2025*

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!
