Why Vacuum Blending? Vacuum blending helps preserve vitamins, nutrients, antioxidants, and natural enzymes compared to traditional blending resulting in more nutritional, healthier smoothies, spreads, and sauces. Why VOID? The VOID Vacuum Blender lid generates 2x the pressure in HALF the time of other vacuum blenders, works longer between charges, and has a built in fault warning. Vacuum blending also prevents blends from separating into layers and keeps it color by removing oxidation, it gives it a healthier taste, and replaces the frothy, foamy consistancy with a smooth, commercial grade blend. VOID Vacuum lid has a bright LED screen to show you battery charge level, digital OLED readout, cycle count and 4 customizable presets to set for your specific blend. A full charge can last up to 100 blends.
