Effective Membranes
Effective replacements! Helped my milk supply bounce back after replacing my pump pieces with these new membranes.

My pump feels like new again!
My medela membranes actually lasted around 6 months before I had to replace them. I was hoping that it was just the membranes and not my whole pump I had to replace and thank goodness once I replaced them they work like gold again and the pump has been great. Suction is good and it’s easy to clean too. Definitely recommend getting this if you feel like your pump suction is starting to get less. They are also great value for less

worth the money
Tried a cheaper off-brand and it didn't work despite multiple ways of manipulating it trying to get it to work. Got these and they work right from the start. Definitely work the money if you don't want your supply to dwindle.

Se ajustaban muy bien. Comparadas con otras marcas, estas me funcionaron muy bien para extractor de medela.

Expensive
Too expensive for a pump part which you need to replace frequently

First time exclusively pumping and I didn’t know you have to change the membrane. I saw a decrease of my supply but when I bought this membrane my supply came back up. Great product but you have to change every 2 months!

Replacement part for Medela Flex. Exactly as original, no issues at all. I had to replace after a year of using.

Works as expected

When I pumped with my first daughter, I had to replace the whole housing as they didn’t sell the membrane separately. I was so excited to see that was updated over the last couple of years. It’s much cheaper and more environmentally friendly. Amazon also has the best price that I could find.

Worked as they should when I replaced the originals to pump for my second child.
