Review on Medela PersonalFit Flex Replacement Membranes, 2-Pack, Compatible With Pump In Style MaxFlow, Swing Maxi And Freestyle Flex Breast Pumps, Authentic Medela Spare Parts,2 Count (Pack Of 1) by Jessica Rogers

They were a completely different color than the original ones that came with my pump and the suction is terrible! I can turn my pump on the highest setting and the suction does not change. I hear and see them not sealing around the shield properly. I’ll be going back to the ones o was trying to replace until I can get some directly from the medela site because these seem like knock offs!
