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 Christopher Foreman

I bought a Medela Freestyle Flex Breast Pump for my second pregnancy. So far, I like it very much, especially when we go out. It is quite convenient to use it. However, I was looking for the backup packs. They are all comparatively expensive and overpriced. I understand the techniques behind each part. But I just cannot believe two pieces of replacement membranes. They can be worth over 11 dollars before taxes. I will have to keep the other parts well, otherwise I might not have the budget to buy all parts as a backup.
