Always ensure that your accessories are properly secured before starting your pumping session. Normal and proper use would prevent any milk from flowing into the tubes and pump.
When bringing the pump out in a bag, we would encourage you to place it into the sleeve provided (white sheet) to prevent risking visible scratches/damages to the pump's exterior.
Please avoid charging and pumping at the same time as this would result in a shorter battery life over time. Only charge when the battery is low/flat, and unplug the pump from the charger when the battery is full.
