Just got these 4 replacement diaphragms for my eufy S1 Pro pump and wanted to share my thoughts!

The good: They fit perfectly and installation was super easy. The silicone feels nice and flexible, just like the originals. Cleaning is a breeze too - no weird crevices for milk to get stuck in.

The not-so-good: The suction power feels slightly weaker than eufy's official parts. Not a dealbreaker, but noticeable when you're used to the originals.

For the price though, having 4 backups is pretty sweet. I'll keep using them while my official ones are out of stock. Will update in a few months on durability!

Pro tip: If you're super particular about suction strength, maybe wait for official parts to restock. But if you need replacements ASAP, these will do the job decently.
