Review on 🤱 Maymom MyFit Flange Set, Two-Piece Breast Shield (Small 21mm) Connector Valve Membrane - Compatible with Medela Breast Pumps (Pump in Style Advanced, Lactina, Symphony) - Non-OEM Pump Parts by Lisa Zulo

I needed 19mm breast pads so I bought the whole set as the price was cheap. Pros: There are 4 membranes in the pack. Cons: If you use this product you risk a broken breast pump. The holes for connecting the air hose are on the bottom and not on the top like the Medela original. The original air hoses do not fit everything, hence the milk leaks. The bibs are too long. If the funnel connector is not completely dry (difficult), water will remain in the holes and get into the air hoses, and then into the machine. The valves are very difficult to separate once connected to the funnel connector. Just pulling it out doesn't help.
