this is my second baby and I have been blessed with being a little over producer! but I have always used Medela! it has been nice and was satisfied by its productivity, but after an incident(my toddler dropped it while I was pumping, she was trying to play with me!! 
) I had been looking to get another cordless pump, so I just went for it, was very nervous! while waiting for the mom cozy m9 to arrive I tried the medela self express pump I hated it! never felt emptied and my breast where In constant pain! my pumps arrived within 24 hours cleaned it and sanitized it, downloaded the app, tried and I hate the fact that I didn’t do it earlier! I love it! and for anyone out there just try it, it was so worth it for me I hope its worth it for you!!!
