4. Product Overview & Features
4.1. VibesFlow Micro-Vibration Technology
The F1 breast pump features VibesFlow micro-vibration technology, which uses gentle air vibrations to ease discomfort, relieve engorgement, and help prevent clogged milk ducts. This promotes smoother milk flow for a more comfortable and productive pumping session.

4.2. Hospital-Grade Suction
The F1 pump delivers up to 320 mmHg suction, mimicking a baby's natural nursing rhythm for effective milk expression. This hospital-grade power helps achieve faster let-down and stronger expression, reducing overall pumping time.
4.3. Independent Dual Control
With two independent pumping systems, you can set the suction, speed, and mode separately for each breast. This feature is ideal for addressing uneven milk flow or varying sensitivities between breasts.

4.4. Multiple Modes & Settings
The pump offers 4 distinct modes: Massage, Expression, Simulation, and Multitronic. Combined with 9 suction levels and 5 speeds, these options provide total control to customize your pumping experience for maximum comfort and milk output.
