Excellent breast pump. Used. Closed system. Lots of used parts, but can be used for just the pump if you want to purchase all new personal parts. Maymom on Amazon has all new parts. Included 3 sets flanges (19, 24, 28mm), 2 sets milk collectors/bottles, 2 sets tubing. 3 sets backflow protectors, bottle tops, lots of duckbills, power cord, and instruction booklet. Pump has a built in nightlight which is great to see the screen at night and what you are doing. Super quiet. Loved it. Cash only. No cash apps.
