The S2 is designed to meet the needs of moms wanting to feel sure that they have an effective, powerful breast pump to support supply.

Like all Spectra pumps, the S2 is a closed system - a physical barrier between the milk and the pump ensures hygiene and motor performance. The S2 is hospital strength - strong and efficient enough to support milk supply. With a maximum suction strength of 300mmHg and the ability to be used as a single or double pump. The touch button with the S2 pump's digital controls allow you to set the pumping program to the speed and rhythm most effective for your body. 
The pump will start in 'massage mode', a short, shallow mode designed to stimulate your body's letdown reflex (start the milk flowing) just like how your baby tells your body to start milk flow. The pump will then switch to expression mode, a deeper, slower pattern of suction which mimics how your baby nurses when the milk is flowing. 
This pump is also NEARLY silent... You can see on the picture that you can adjust both cycle (how often the pump 'sucks') and vacuum (the strength of the suction) easily, and the digital display allows you to see your program at a glance.

Warranty: 2 year warranty on motor and 90 days on accessories.
