Key Differences – Spectra S2 vs S1
Spectra S2 vs S1 – Operation Mode
When it comes to breast pumping, Spectra is a top choice for many moms. Both the S1 and S2 models offer effective options for pumping, but the S2 pulls ahead when we dig into the details of the operation modes.
The S1 has the basics covered with massage mode for letdown and expression mode for extracting milk. Massage mode cranks things up to a swift 70 cycles per minute to get the milk flowing. Expression mode lets you adjust between 38-54 cycles per minute to find that sweet spot.
But when we look at the S2, it really brings the noise with more variability in the settings. S2’s massage mode sticks to a rapid-fire 70 cycles per minute to stimulate letdown. However, its expression mode opens up the possibilities with vacuum strength adjustable across 12 levels, in addition to tweaking the 38-54 cycles per minute speed.
For moms wanting options to customize their pumping session, the S2 is pumping out more power. While the S1 takes a simple approach, the S2 lets you become a pumping DJ to mix and match the settings.
