While this looks like the parts for the Elvie, for whatever reason it did not create suction. I was not able to breast pump with these. It's thicker than the elvie parts and can't create suction. Like that they were pink but that's all.

Bought these for my Elvie and the duckbills worked great, however the other piece did not create a suction with my pump and had to go back to using the original valve that came with my pumps

Should've read reviews before purchasing - these did not provide needed suction for the Elvie pump to work. Not a suitable replacement part - defective & useless.I agree with this other review 100%:"I bought this product trying to save a few dollars for my Elvie wearable breast pump and I might as well have thrown that money into the trash can. It’s not the same type of silicone as the name brand product and it doesn’t allow any suction while you’re trying to pump. In essence, it doesn’t let your pump work and so it’s absolutely pointless to use or purchase."

I love these more than I thought I would. I bought these as replacements since you’re supposed to replace them every few months. I chose these for several reasons; the first being that they’re cheaper than the elvie ones, and second because they were pink so I could keep track by color which ones I had replaced most recently.They’re great and I think they increased the suction of my pump. Not just because they’re newer, I also was given a brand new set of the elvie brand diaphragms shortly after I got these and I feel like these work better!! I’ve had no issues with leaking and my brand new elvie brand diaphragms leaked. So I’m sold on these!! I just wish they came in different colors so I could replace a few at a time and keep track of which had been replaced.Overall great value and I’m definitely going to order more!

I like the soft texture of these, but I like being able to see inside my flange. I wish they were clear instead of pink.

I bought these inserts for my Willow Go pumps, they work great. I haven't had any issue with suction or them coming off/loose.
