Medela's Swing Maxi double electric breastpump has a 2-Phase Expression function that allows you to collect up to 18% more milk than single pumping. Short, stimulating patterns are followed by longer ones to ensure optimal milk flow. The small and compact design is easy to use, transport and store. It's quick to assemble and easy to clean, so it's ideal for use on the go with batteries, or at home using the mains adaptor. One Calma Solitaire teat included, which mimics the unique breastfeeding sucking behaviour of a baby. Also includes two bottles and two bottle stands. The comfortable design features a range of vacuum levels and settings. Quiet operation for added privacy. Can be used in double and single modes.
