Medela swing maxi double electric breast pump

In excellent condition and comes with extra bits More milk in less time. Just like its predecessor Swing Maxi Flex™, the new Swing Maxi™ is a double pump that allows you to extract milk from both breasts simultaneously to make your pumping twice as fast. In addition, pumping both sides at the same time is proven to yield up to 18% more milk1. 2-Phase Expression® technology. During a feeding session, babies start by using short, fast sucks to stimulate the Milk Ejection Reflex. Once the milk begins to flow, babies change to a slower, individual rhythm to actually feed. Medela's 2-Phase Expression® technology mimics baby's natural sucking rhythms - fast to stimulate milk flow, then slower to provide optimal milk flow.
