Maymom(Blue) - Silicone Membrane; Designed for Spectra S1 Spectra S2, 9 Plus Backflow Protector and Backflow Protectors, Long, Short and Medium. Blue

These work great for my Spectra Synergy Gold. I like to have a set of colorful ones and white ones so I can alternate and be able to keep straight which one I'm supposed to use next so that I don't overuse one set. This silicone is a good quality one. Some brands that I've tried the silicone was thin but this is very similar to the Spectra original membranes and the suction works the same too. The 2 pack is a little bit pricier than if you get the white ones but for what I needed, it was worth it for sure. The only reason I didn't buy this company's set of duckbills and membranes is that the duckbills don't have pull tabs on them so I buy them separate so as to not stretch the duckbills out when trying to get them off of the flange to clean them.

Amazing quality and super cute pink to match my spectra s2.

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!!

My wife gets these for pumping. She is exclusively pumping so she's pumping 7 times a day and she likes to have 2 sets of duckbills and backflow membranes, so she gets different colors to keep them separate and to be able to keep straight which ones she used last so that she uses them evenly. She replaces the duckbills every month and the backflow membranes every other month. She gets a set from another company that doesn't come with enough backflow membranes so she gets these. They are a little pricey but she likes the colors to keep them straight.

I purchased this as a replacement part for my Pink Spectra. Also because I’m pumping for my son so I loved that it was blue. Definitely great suction and having multiple colors for this portion helps me remember what pieces I have and haven’t used.
