Offering both practicality and flexibility, the MAM 2 in 1 Double Breast Pump is an electric pump that can convert easily into a manual pump when needed. It allows you to individually adjust the pumping settings for each breast, with different suction strengths and different modes for left or right only pumping, dual or alternate pumping in 30 second cycles which can help stimulate milk flow. Designed with an alarm that can be set to remind you when next to express milk, this pump has a timer that counts the minutes of your pump cycle, nine different suction strengths across both stimulation and expression phases, can convert to a manual pump in two simple steps, and has a rechargeable battery which lasts up to 3 hours - taking away the worries of having to be near a plug socket. Good to know: The MAM 2in1 Double Electric Breast Pump is compatible with all MAM's Easy Start bottles and milk storage pots, allowing mums to express directly and safely without losing a drop.
