The S2 is designed to truly meet the needs of moms wanting to feel confident that they have an effective, powerful breast pump to support supply while also incorporating features to make life a little easier.  With a maximum suction strength of 250mmHg and the ability to be used as a single or double pump, plus a host of additional features, the S2 is set to become the ultimate breast pump to support U.S. moms. 

On Up's Takeaway: 

Moms love the Spectra S2. While it does not have a built in battery like the S1 the S2 is sometimes covered by insurance. You should know that replacement parts might not be available at local baby stores - but hey! you can easily order them here at On Up.
