Small manual breast pumps may seem unnecessary for mothers who plan to breastfeed often, but having a compact and lightweight pump on hand is always helpful. Most mothers need to express milk on occasion. This breast pump is especially suitable for women who travel: it can be used as a reinforcement of a double electric pump, or exclusively, if you do not express milk often. Lightweight and discreet Medela's Harmony is a manual breast pump, so it requires no electricity or batteries to operate and is virtually silent. When you start pumping, you will be surprised how well it works. It is a very light extractor that does not take up much in your bag. Simple and elegant design The ergonomic design of the Medela Harmony is intuitive and easy to use. Disassembling and cleaning it is also very simple. The Medela Harmony Manual Breast Pump handle is designed to rotate so you can always set it at the most comfortable angle when pumping and don't have to put your arms in an awkward position.
