eufy Original Spout Cap (4-Pack) for Wearable Breast Pump E10/E20/S1/S1 Pro, Breast Pump Replacement Parts

Very helpful for more security when moving around! It does not leak or fall out when bending over or moving about. The only downfall is that they are small and sometimes hard to keep track of when not in use.

These work amazing however they’re easy to lose and cost quite a bit for tiny pieces.

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!

Works exactly as promised, doesn't fit super good with the dust over but you can get it in there

Ridiculous that these are $20, especially because the pumps are $350, the stoppers should just come with the pump in my opinion! They work okay, you will get leakage if you bend over but it’s pretty minimal. They do good enough to prevent any leakage from regular movements around the house. I’ve cleaned with them in (but avoided bending over) and it makes a huge difference, especially if your output is enough to fill the collection cups. With that said, if you have a large output and are consistently filling the collection cups, these are a must to prevent spillage during normal movements. Stars lost due to price and because they’re not fully leakproof although it’s a major improvement with them.

I’m not sure why these don’t come with the S1. They plug the spout to help prevent leaks but they aren’t totally leak proof. I use these when pumping and doing chores so that milk doesn’t spill out if I bend over slightly.

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.

Purchased this as a bundle with complete spare parts set for Eufy S1 Pro and it didn’t come with the pump set. Haven’t used my pump to wear i might spill out, but this will for sure prevent that, especially while working and pumping.
