I purchased this item new and used it for pumping 5-6 times a day for the first 3 months. However, the amount of breast milk I could express per pumping session was only about the amount my baby needed (60ml, 80ml), and it wasn't much. Sometimes, nothing came out. I heard that a manual breast pump might suit some people better, so I bought one of those too, but it also didn't produce much. Therefore, I will give away the manual breast pump and breast milk freezer packs (new) for free to anyone who purchases the electric breast pump. After that, I started taking care of my baby alone and didn't have time to wash the breast pump, so I switched to direct breastfeeding. *Please note that the silicone parts show some discoloration, which is my personal observation, after 3 months of use. Please be aware of this before purchasing. *There are arrow marks on the silicone parts, so please align the marks when assembling to ensure proper attachment. - Brand: momcozy - Model: S12 Pro - Type: Wearable Breast Pump - Connection Port: USB Port - Condition: No cover Thank you for looking.
