Membrane Compatible with Medela Pump Parts, 2-Pack BPA Free Silicone Membranes Compatible with PersonalFit Flex connectors, Yellow

This is a much needed replacement part for you Medela Pump. I would recommend replacing every 2 to 3 months depending on usage. Happy I was able to find on Amazon

I am apparently one of several users who were highly dissatisfied with these membranes, and I think I can explain why other buyers think they're great: the manufacturer seems to be exercising poor quality control.Like other women in the reviews, I found these incapable of producing any suction to speak of. Fortunately I had not yet discarded my Medela membranes, so I wore one of those on one side and one of these generic membranes on the other and ran my machine with the diagnostic assistance of my husband. He informed me that the little flap at the bottom of the generic membrane was not sticking down, thus there was no seal, and thus, no suction.I have started the return process and I wuld leave zero stars if I could. Buyer beware, only get this one if you still have the name brand version as a backup.

Despite some of the review stating these are not compatible with Madela, they work with my Madela Pump in Style just fine. They are actually thicker than the ones that came with the pump which did not last at all. The thin Madela ones actually warped so much from constant use. These are more durable and have lasted.

Unfortunately it did not work in my medelas. It was too thick of quality, so it was not able to suck in the air. I had to return and buy new and it was the same thing with the second pair.

I’ve ordered these a bunch of times and only had one not fit right but I boiled it for a few minutes and it fit okay after that. Much cheaper option to the brand name

These do not generate any suction whatsoever. After reading through the rest of the reviews it seems to be a common yet inconsistent problem which suggests poor quality control. Definitely not worth the hassle. Would not recommend.

Well priced and great quality, will buy again

I was disappointed with these because they were so thick and didn’t seem to quite fit my medela pump correctly. I felt like I had to shove them in and didn’t get the same output as the factory ones
