Maymom 8 Count Duckbill Valves for Spectra S1 Spectra S2 Spectra 9 Plus. Not Original Spectra Pump Parts Replace Spectra Duckbill Valve Not Original Spectra S2 Accessories Work w Spectra (White)

I love these.They work so amazing with my pump.Even they're not exactly made for my pump.They still work phenomenal there pretty cheap.They are so heavy, which is really nice.Cause they are not wearing down anywhere near as quickly as my others love them. They have been such a lifesaver , and they make it feel like my pump gets more suction with them

Works perfectly with my spectra! No complaints

Worked perfectly with my medela pump.

I feel like these last way longer than the name brand spectra duckbills, I just ordered my second replacement duckbills and I am very happy how my previous ones lasted way longer than my spectra duckbills.

I needed more duck bill valves for my spectra, these have worked great, they’re compatible with my flanges that I already have. They wash and sanitize well. I think they work better and have better output for me than the ones insurance has been sending which are super cheap. Also it was awesome to get several sets for such a low price. I appreciate these came with a little case too! I will definitely be reusing the case even after I’ve used all the valves.
