Nenesupply Handsfree Valves and Membranes Compatible with Medela Handsfree Collection Cups Freestyle Handsfree Wearable Breast Pump. Include 2 Membranes and 2 Valves. (2V2M)

loved this so much

Terrible. Just terrible!! They are different material than the one piece set. They make fart noises and you can see the diaphragm touch the top of the plastic cover because they are so stretchy.

Im not sure if it is user error or something with this product, but I find these incredibly difficult to place onto the pump and have it seal correctly. I am constantly having to take the pump apart and readjust the pieces onto the pump. Even still it always feels like something is off and the pump is not working efficiently with these in.

They work ok. I was desperate to find replacements since I can't find actual medela ones anywhere. Every time I have used them they make a noise like a pig grunting. Mooing I would understand, but the pig noise is odd. I will be looking for a better replacement part. Get them only if you have to have a replacement.

I was surprised to see this have 2 parts instead of the one piece the medela handsfree cups come with. However these do fit and seem to be a good backup.

Absolutely horrible! Didn’t fit snug like it should and did not work with my Medela hands free cups. They wouldn’t even suction with these replacement parts. Stick with original Medela replacements for these.

I would not recommend these membranes because there’s inconsistent results with suction. Similar to other reviews I have to adjust multiple times to ensure everything is working.

They do fit the Medela hands free collection cups but I would say not as snug because they make a lot of noise when using. It is also two parts instead of one as shown in the photo, it's not a problem as long as I don't loose the little one. Ships much faster than Medela!
