### ⭐⭐⭐⭐⭐ Works well with Spectra S1
*by E***E on July 1, 2025*

When the membrane diaphragms that came with my Spectra S1 pump just weren’t adequately doing the job anymore, I found these! After reading through the reviews, I decided these would best fit my needs. I like that they feel a little thicker than the Spectra ones, so I’m hoping they may last longer. I also like that they have different colors! I went with the pink to match my duckbills from Legendairy. I’m very pleased with these and will order again in the future!
