This is a very simple pump to use and easy to assemble. When without an electric pump, this is a great option due to the strong suction from the pump. The suction actually mimics the way a child would which is quite amazing, with short and long sucks. This pump can be used wherever, however is a little less discrete than the haakaa breast pump as you will need both hands to manually pump the handle to express milk which can be tiring. Also, this is not recommended for everyday use.
