Hi! I just bought two of these momcozy S12 breast pumps, and while the reviews are amazing and I have gfs who use them- they just didn’t suction right on me. I only used these once, and cleaned, disinfected and sanitized all parts. I still have the original box with instructions and everything in it. Make me your best offer! :) The Details: Double-sealed flange pumps faster Quieter and more discreet 3 modes and 9 levels of intensity The timer function tracks well Hospital grade
