Since my little one had trouble because of a shortened lingual frenulum to drink at her breast, I was forced to pump over a longer period several times a day. The electric pump (Medela Symphony) was effective, but too unwieldy, localized and loud. Also, I felt like at the milking machine. The Harmony is super quiet, discreet, small disassembled and therefore easy to transport and use on the move and at night just fine. Although manually, I can without straining the same amount of milk pumping at the same time as with the electric pump. An extra plus is the easy cleaning. Problems with the vacuum I had not, despite frequent use and sterilization. In addition, my experience has been very positive with the customer service at Medela.
