5.2 Blend‑and‑Go Convenience
The ability to blend directly in the cup simplifies morning routines or travel. The spout lid allows consumers to transport beverages without transferring contents to another container.
5.3 Pro Extractor Blade Technology
The Pro Extractor blades work differently from the Total Crushing system. They are specifically designed for:
- Breaking down seeds
- Pulverizing tough fibers
- Mixing dense or frozen ingredients
These blades often spin at high speed and create a vortex that draws ingredients downward for consistent blending.
