Disappointed
I bought these thinking they would be better because they're thicker, but they give me the same problem as the cheaper ones. They lasted barely a week. They are washed correctly as I do not push anything through the valve.

Perfect!
Got these in case I loose the ones I have for my mommed and these fit my pump perfectly! I used one for the pump and it works just like the original that came with my pump. Definitely a good price!

Fits
They fit my wearable pump and where half the cost on their actually website. I'd recommend

Doesn’t work for specific pump searched for
This doesn’t fit all Lansinoh pumps and when you search the kind you have this still comes up so I’m here to show you what this product really looks like to help other Mamas before they buy and wait to have to keep waiting. This valve duckbill has a collar and is more narrow. The product is to the left and mine needing replaced is on right. My pump is the Thrive 2 in 1 portable. Not compatible.

Passt auf die Bellababy 🥰
⭐️⭐️⭐️⭐️⭐️ Ich bin sehr zufrieden mit dem Milchpumpen-Ventil! 💕 Die Qualität ist wirklich top – das Material wirkt robust, flexibel und langlebig. Es passt perfekt auf meine Pumpe (keine Undichtigkeiten oder Saugkraftverluste) und lässt sich leicht reinigen, was im Alltag mit Baby super wichtig ist. 🍼 Ich habe schon andere Ersatzteile ausprobiert, aber dieses Ventil funktioniert am zuverlässigsten. Die Milch wird effizient abgesaugt, und man merkt sofort den Unterschied, wenn das Ventil gut schließt – kein Luftziehen, kein Tropfen. Auch nach mehreren Reinigungen bleibt es in Form und dicht. Der Versand war schnell, alles kam hygienisch und einzeln verpackt an. Besonders toll finde ich, dass es ein günstiges, aber qualitativ hochwertiges Ersatzteil ist – ideal, um immer ein paar auf Vorrat zu haben. Fazit: Sehr empfehlenswert für alle, die eine zuverlässige Funktion ihrer Milchpumpe möchten. 🩷 Praktisch, sauber, langlebig – würde ich jederzeit wieder kaufen!
