Electric Breast Pump Thank you for viewing. I purchased this in 2024 and used it a few times. I am selling it now that my milk supply has stabilized. I wasn't sure what would work best, and I also used a manual breast pump, so I am also selling breast pumps from other brands. The electric pump made it easier for me to express milk, so I quickly got into the swing of breastfeeding. Because of this, I only used it a few times and it should still be in good working condition. As shown in the diagram in the instruction manual, you can pump well by assembling it while firmly pressing with both hands. You can switch between pumping mode, automatic mode, and massage mode with the touch of a button. The strength of the pumping can be automatically adjusted in automatic mode, but you can also adjust the strength in 16 levels, allowing you to pump according to your own condition. No returns accepted. USB charging cable included. Operation confirmed. Please understand that this is a used item and has been inspected by a non-professional. There is a dent in the outer box, but the main unit is in good condition. Please understand that this is a used item.
