Medela Spare Membranes, Breast Pump Replacement Parts, Made Without BPA, Authentic Medela Spart Parts, White,6 count(Pack of 1)

Works great!

I'm so glad I can easily order these on Amazon because I loose them so often when I wash my pump parts. I'm glad they aren't expensive either. I love my Mandela hand pump and the parts are easy to use, wash and assemble.

I recently found out (oops!), after using the same pair of membranes for 9 months, pumping 3 times a day, that membranes should be replaced periodically. Medela says monthly. But, it really depends on how rough you are on them when you wash them, if you use a bottle brush on them at least once a day yes, I would say you probably will rip one before the month is out. However, I was putting soap on my pinky and being very gentle while washing. However, I had noticed over time that I was collecting less milk. I attributed this to me having a cold and my baby getting older. After replacing the membranes and trimming the ends of my tubing (where it connects to the pump) I didn't have to take the fenugreek and blessed thistle anymore to increase my supply. This product is exactly as described. It is the original replacement Medela membranes. I looked at the cheaper off-brand listed on Amazon but decided that I would probably get about 3 months out of a pair and one pack of these would last me until the end of my need to pump for this baby. They work as expected and were priced well. Thanks!

as described

I did not realize how often I needed to change this part and once I did it was back to that powerful suction! I have a Medela pump so the replacement part was the perfect fit, it was easy to install and for the price there is multiple replacement sets in the package. Overall very happy with my purchase

Perfect size! Exactly what I needed!

I saved a lot by ordering these from Amazon. They are perfect for my pump and came very quickly. Exactly as expected!

Works exactly as it is supposed to for my medal advance part.
