Let me start by saying these duckbill valves are a game-changer for busy moms like me. I’ve been using them with my eufy S32 pump, and the fit is absolutely perfect—no awkward adjustments or leaks mid-pump. The suction feels just as strong as the original parts, which surprised me given the affordable price.

The BPA-free silicone gives me peace of mind, especially during those 3 AM pumping sessions when I’m too sleepy to double-check materials. They’ve held up through multiple sterilizations without losing shape—unlike some generic valves I’ve tried that warp after a few uses.

What really sold me? The 10-pack value. After constantly stressing about losing tiny valve parts in my diaper bag, having backups everywhere (car, office, grandma’s house) has been a sanity-saver. Pro tip: Store them in a small wet/dry bag—they dry crazy fast after washing!

Minor gripe? The duckbills are slightly stiffer than OEM valves when new, but after 2-3 uses they soften up nicely. For under $10, this set outperforms single replacements costing twice as much. Five stars for keeping my pumping routine smooth and leak-free!
