Maymom Silicone Membrane Suitable for Spectra S1 Spectra S2, 9 Plus Backflow Protector and Maymom Backflow Protectors, Long, Short and Medium; Not Original Spectra S2 Accessories or Spectra Pump Parts

Who doesn’t love getting new pump parts? These are the same quality If not better than from spectra at only part the price making it a lot easier to replace more frequently. I feel like they are a bit sturdier, almost seem thicker.

Packaging is super sketchy. Not even sealed and the container looks like it’s been reused. Open it up and there is lint/hair on the membranes. They do fit with my spectra back flow discs. I haven’t tried using them yet to see if they work properly.

My pump time doubled and my output halved. Junk. These are way too thick and inflexible compared to the originals. They get the job done in a pinch but they are not a good product. Please please please just pay more for the spectra brands I am so mad. I already threw the packaging away for both sets I bought and I’m kicking myself. Now I can’t return either set.

I change all the silicone parts of my breast pumping equipment every 5-6 weeks....so these work great instead of having to buy the entire backflow part through Spectra. I'll buy them again for next time.

Good replacement for my Motif Luna. Also fits Spectra S1/S2. Will reorder when I need my next set
