Works well with Spectra S1
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!

Reliable product
The MayMom company continues to impress me. This is a reliable product. I truly appreciate the variation they have in color now, which helps me keep track of how long I’ve been using each of the parts. Backflow protectors should be replaced every six months or less, and the color helps me keep track of which set I’m on. If your milk production starts decreasing, change out parts! I was having a dip in my supply and switched them out to this maymom product and it’s right back where it should be. Will continue to be a Maymom customer!!

Fit Motif Luna
Purchased these for my Luna Motif. Was unsure they were compatible since it was not listed in the written description, but was included in the photos listed by the seller. Can confirm they fit the Motif Luna and work well.
