The safety feature is that GVX2 will not operate unless the lid to bean hopper and coffee container are in place. This avoids unwanted grinding, which can be dangerous. Another shared feature between the two coffee grinders is the quantity selector, which allows you to choose from two to twelve cups, and then shuts off automatically after grinding the right amount of beans. The fineness selector gives you seventeen texture options, from fine to coarse. In order to preserve the coffee's aroma and flavor, the Burr Milling System of the Krups GVX2 works to avoid overheating.
