Thank you for viewing. This item was purchased in September 2024 in preparation for childbirth. However, I didn't produce much breast milk and quickly switched to formula, so I only used it a few times. It's a rechargeable, hands-free type that you can put in your bra, allowing you to do other things while pumping. It makes pumping easier for mothers who are physically weak after giving birth. Power-on and all functions have been confirmed and are working without any problems. The breast milk collector (cup) has some scratches. This is a used item, so please refrain from purchasing if you are sensitive to such things.
