Review on Nenesupply Pump Parts Compatible With Medela Breastpump Not Original Medela Pump Parts 24Mm Breastshield Valve Membrane For Medela Pump In Style Medela Symphony Swing Replace Medela Breastshield by Jonathan Devarapalli

I use the Medela Pump in Style Advanced and purchased these parts as replacements. I actually prefer these to my originals because the hole in the back of the breastsheild (it's one piece) where you insert the tubing is at the top instead of the bottom. This made pumping easier for me. I pump at work at my desk and tend to hold the two breastshields with my forearm and have 1 free hand. Having the connectors at the top keep the tubing from being pinched. I found this to be a helpful design. Also, I had no trouble cleaning the parts. I often used the Medela Quick Clean Micro-Steam Bags.
