As a mom who relies heavily on my eufy S1 Pro pump, I was curious to try these replacement diaphragms after running out of the original ones. Let me break down my experience with them.

The fit is spot-on - they slide into place just like the OEM parts. No awkward gaps or alignment issues during installation. I appreciated how the silicone felt soft against my skin, similar to the originals.

Where I noticed a difference was in suction power. While decent, it's not quite as strong as eufy's own diaphragms. It's like comparing a firm handshake to a slightly looser one - still gets the job done, but you can feel that subtle difference.

Cleaning is a breeze though! The smooth surface doesn't trap milk residue, and they've held up well through multiple sterilization cycles so far. After two months of daily use, they're showing minimal wear.

Would I recommend them? If you're in a pinch or can't find original parts, these are a good temporary solution. But if suction efficiency is your top priority (especially for those with low milk supply), it might be worth waiting for genuine eufy replacements.
