Okay, let me just say THANK YOU to whoever made these off-brand duckbill valves. After weeks of waiting for Eufy parts (still MIA btw), these arrived NEXT DAY. Like, magic.

First impressions? They look identical to my original Eufy parts. Popped one set in immediately because my old duckbills were basically retired after a week (ugh). Worked perfectly on first use – strong suction, no leaks. I EP so this was critical.

The material feels like quality silicone – no weird smells or stiffness. Washed easily too! Only used one set so far but at this price for 12 pieces? Even if they last half as long as OEM, still winning.

PSA for fellow pumping warriors: These fit my Eufy wearable pump AND apparently some Shein/Befano pumps according to reviews (though YMMV on diaphragms). Stock up before the formula companies come for these too!
