Great product
Super pleased with my purchase. I bought these to replace the original ones that came with my pump. I like these even more & they feel more durable. Would definitely recommend the overall Eufy pump. I have the S1.

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.

Great Buy for an Exclusive Pumper
This was a great buy when my duckbills in my pump were getting wear and tear. I had no idea how fast they could get worn down, but was super happy to see replacement pieces here!

Perfect with s1 pros!
These were the perfect replacement in my Eufy S1s and immediately noticed an increase in milk pumped when replaced these!

Perfect fit
These little guys are super easy to break and was so sad when I found my original one ripped. I was happy to find that amazon had the original parts and for a great deal with multiple quantity options.

⭐️⭐️⭐️⭐️⭐️
These replacement parts for my Eufy wearable pump were exactly what I needed. They fit perfectly, work just like the original pieces, and restored the suction back to full strength. It’s so nice having extra parts on hand so I’m not constantly washing the same ones throughout the day. The quality feels really solid, they’re easy to assemble and clean, and they’ve made my pumping routine so much more convenient. Definitely worth it for any Eufy wearable pump user! 🍼✨

Quickly Defective
Most of these valves only lasted three pump sessions before losing their seal and being useless. Definitely not worth the price!

Great replacements!
The duckbill valves are such good quality! The suction of my pumps is back to when they were brand new, I think it’s even stronger and I only use them on level 4. (I have the eufy s1)
