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 Brian Delgado

These work really well for single pumping, but not double pumping. I can't take these to work with me because I can't hold them both and double pump. With the pump attachments where the sheild separates I am able to wear/connect the pump to the bustier and pump both sides at the same time and work/type while doing so. I love the madela pieces for work. It's difficult to try and hold each of these while pumping and then adjust the power and turn it off, ect. I would recommend them for use at home (when you don't need to worry about pumping within a time frame) and just doing one side at a time. Other than that, I like them and think it's conveinent to have one piece.
