The Only Wearable Breast Pump With Heating (HeatFlow)

What sets the S1 apart from the S1 Pro
The S1 delivers the same HeatFlow heating, OptiRhythm app control, 300 mmHg hospital-grade suction and 7 intensity / 3 speed settings as the S1 Pro, but does not include the charging case. The S1 runs on its own built-in battery for up to 4-6 pumping sessions per charge (the S1 Pro adds a charging case for up to 5 days of power), which is why it sits at a lower S$418 vs the S1 Pro's S$555.
