4Pcs Replacement Diaphragm for eufy Wearable Breast Pump E10/E20/S1/S1 Pro - Food-Grade Silicone, Easy to Clean & Install

works with the eufy s1pro. Essential in your pumping journey. Good price and good quality

These replacement diaphragms fit my eufy pump perfectly! The quality is great, they work just like the originals, and installation was super easy. Such a good value for the price — my pump is working like new again. Highly recommend for anyone needing replacements!

Not as thick as originals that come with the unit itself but still works.

They fit my eufy pump perfectly!

These diaphragms are too big for my eufy. They seem to work okay but my motor doesn't fit properly with these. I ordered more authentic eufy ones because I just don't trust it. Such a bummer. Update: these def don't work as much I have consistently gotten less milk overall since using these. As a just enougher i cannot risk anything that hurts my supply. I attached a pic showing how they are too big and will not push down all the way

Exactly the same as the name brand eufy diaphragms

These fit alrk just like the ones that came with my pump now I am able to have two sets of cups and flanges so I can have one set dirty and one clean.

These are fine and mostly fit, but it does impact the way the motor snaps onto the pump frame. You really have to push it in and often it won’t line up to use the eufy heating function. I wish I’d gotten the brand issued ones from the start and saved myself some frustration

Do not recommend - I used these replacement diaphragms and noticed a significant decrease in output. I put my old eufy diaphragms back in and re pumped during the same session and got so much more. Not worth it at all!
