Works just as well as brand name
Much cheaper than the Spectra name brand parts and work just as well with my Spectra S1 pump. The cute color is an added bonus.

Great Affordable Alternative to Brand Name Parts
These replacement duckbill valves are great. They were delivered quickly and are a very cost-effective option compared to the brand name parts.They function just the same as far as I can tell in terms of output, so I have not noticed any difference at all when using them.I also really like that they come in different colors. It makes it easy to keep track of which parts have been replaced and which ones still need to be, which is super helpful when rotating pieces. Overall, a great value and I would definitely purchase again.

Works well with Spectra S1
When the membrane diaphragms that came with my Spectra S1 pump just werenโt 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 Iโm hoping they may last longer. I also like that they have different colors! I went with the pink to match my duckbills from Legendairy. Iโm very pleased with these and will order again in the future!

Spectra Compatible!
Bought these to use with my Spectra S1 and they worked perfectly! Finding affordable and fun (pink!!) replacement parts for your pump is always a win in my book!

Great quality!
Love these, such a great replacement option! Canโt tell the difference and the colors help me figure out which ones are new when I boil all together.

Amazing
These work great! I have the spectra s1, I bought these as a replacement and they have exceeded my expectations. First, they donโt attract lint and and pet hair like the original ones and they also work well as a backflow membrane. I had a stream that was spraying out a little high and when I finished pumping there was almost 1/3 of the space full of milk. However when I removed the milk and took the membrane off, the space behind it that leads to the spectra was bone dry.
