This is an easy-to-use breast pump with a double pumping function. It's the Medela Swing Maxi Flex electric breast pump. Purchased in 2022 and used for about six months. One bottle lid is missing. The other parts are all present, and the pump has been tested and works without any problems. Please note that there are minor scratches and discoloration from use, so please understand that this is a used item. Only those who understand that this is a used item stored at home are welcome to purchase. I am not currently considering lowering the price. Thank you.
