Nenesupply 4pc Duckbill Valves Compatible with Wearable Elvie Breast Pump and Pump Parts Replacement Parts. Made by Nenesupply. Not Original Elvie Valves. Use with Pump Seals.

They do what they're supposed to. For that they are excellent.

Work well although pretty pricey not as expensive as from elvie

Merke von der Qualität kein unterschied zum Original

these are really good as compared to the original. infact I feel it is made up of better quality material. this is my second purchase. the valves work better because I get more letdowns and outputs from my elvie pump. BUY IT! the differences are, these are slightly lighter in color and there is a small imprinted number on it. this is kindda helpful if you still have the original ones with you, so you can set them apart.

Perfect alternative to buying the overpriced elvie replacements - especially if you live in Canada because the shipping and duties were going to be crazy on the original ones. These have been working great for a week so far

These duckbill valves are a great dupe for the Elvie. Both photos show the manufacturer duckbill valve on the left, and the Amazon product on the right. There are slight differences, but they work perfectly with my pumps. They give great suction and I get the same output as with the originals. The rubber is slightly stiffer than the Elvie brand duckbills, which I found actually hold up better through repeated use and washing. Hard to beat for the price!

Worked perfectly for my Elvie, not as expensive as the Elvie brand replacements, AND lasted longer than the Elvie brand duckbill valves!
