Customer Reviews (4.8 / 5 · 5 reviews)

Sophia U. ★★★★★

The duckbill valves fit perfectly and the food-grade silicone feels sturdy, not flimsy like some replacements I've tried. Having the two-pack means I always have a clean set ready for middle-of-the-night pumps.

Violet ★★★★★

I was skeptical about spending extra on replacement valves, but these food-grade silicone ones are so much easier to clean than the originals that came with my pump. Having the 2-pack means I’m never stuck hand-washing mid-drain session, and my flow stays consistent until it’s time to swap again.

Ella Q. ★★★★★

I was tired of dealing with slow suction, but these new valves made the pump feel like new again. The food-grade silicone is noticeably softer than the old ones, and the milk flow is consistent every session.
