Thank you for viewing! I purchased this new in 2021. It's an older model, but I found it very easy to use and maintain. There are some minor scratches on the bottle, but I think it can still be used. I used it about 10 times. It has been sterilized by boiling. All parts are included. The nursing pads are unused, so I've left them in. Instruction manual included. Will ship without the outer box. [Rotary Handle] Breast pump. Can be used with either hand. Easy-to-grip, easy-to-use, and fatigue-resistant design. [Lightweight and Compact] A small and convenient breast pump that fits in your bag. You can pump comfortably anywhere. [Simple to Clean] Medela breast pumps have few parts and can be washed by hand, sterilized by boiling, and also cleaned in the dishwasher or sterilized in the microwave. Please wash after use and sterilize once a day. [Medela's Unique Pumping Technology] It is important for a breast pump to accurately reproduce the natural rhythm of a baby sucking. The Harmony breast pump reproduces the "2-Phase Expression Technology" which uses two levers of different lengths to recreate the natural rhythm of a baby drinking breast milk.
