The Medela Harmony Simple Manual Breast Pump is designed for mothers who breastfeed most of the time and is great for taking on the road or as a complement to your regular electric breast pump. Discreet, comfortable and smooth For mothers who plan to breastfeed all the time, small manual breast pumps may seem unnecessary, but it's always a good idea to have something light and compact on hand. Most mothers will face situations where they need to express milk for their own comfort. This pump is especially recommended for traveling mothers: to use as a complement to a double electric pump or alone, if you do not express milk often. Light and discreet Harmony is a manual extractor, so it doesn't need electricity or batteries to work and it's very quiet. Its good functioning will positively surprise you when you start the extraction. It's a very light pump that doesn't take up a lot of space in a suitcase. Simple and elegant design Harmony's ergonomic design is intuitive and very simple to use. It is very easy to take it apart and clean it. The Harmony manual breastpump handle is designed to rotate, so you can always get the best angle to extract the milk without having to put your arms in an uncomfortable position. The handle has a nice soft rubber cover that makes it a little easier for your hands to extract and helps the breast pump run silently. 2-Phase Expression Technology Harmony is one of the only manual breastpumps in the world with 2-Phase-Expression technology. The extractor simulates the baby's natural sucking behavior on the mother's breast. The design of the 2-Phase Expression technology simply means that to stimulate the milk to let down (when the milk starts to flow) you must start the pumping with the shorter side of the pump handle, which creates a faster suction cycle, similar to of a hungry baby. When the milk starts to flow, it should switch to the longer side of the handle, which creates a slower suction cycle to extract most of your milk. It is one of the only manual breast pumps in the world with 2-Phase-Expression technology. It's small, light and easy to carry.
