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 Product
This product works well for my Eufy wearable pump. I have bought replacement parts that were off brand, but buying the brand name has shown a considerable difference in suction power. The replacement parts came super quick once I noticed suction decreased with my worn parts.

Fantastic replacement parts
These fit like a glove! They wash well in the heat. No complaints

Now I can finally bend over w my pump!!
Fit perfectly on my eufy e20 pump. A little pricey but the quality is great. I’d rather get the real deal and pay a little more than get some knock off made out of who knows what.

Incredibly thin compared to original part
I’m not one to leave reviews, but I wanted to share my thoughts on the replacement diaphragms.Let me start by saying I absolutely love my Eufy S1. It’s my primary pump and it gives me great output while allowing me to move freely to care for and play with our toddler and newborn. However, I ordered replacement diaphragms to have on hand for when I need them and I was thoroughly disappointed with what came.The replacement ones are so thin compared to the ones that came with my pump that you can see light shining through them. I couldn’t care less about the color being different, but with how thin these are, I’m worried about them having a negative impact on my supply. I haven’t used them and quite frankly I don’t plan on it. I took them out of the box, took these pictures, and plan on returning them to try a different brand that I’ve heard works with these pumps.New part on the bottom/left in pictures; original on the top/right.

Perfect replacement
I’ve ran into a lot of replacement parts that don’t quite fit, but these work perfectly with my S1. I replaceme them every month and continue to have great output.

Good but could be better
It does stop milk from splashing out most of the time but every now and then it does come out.

Just what I needed
What else can I say, they’re exactly what I needed to replace my eufy E20 duckbill valves. All are in good shape and fit in my pumps like the original ones. Sturdy!
