The reviewers' main criticism is the blower attachment's unintended effect on the grind size adjustment. The subtle movement required to use the blower inadvertently adjusts the grind setting. To mitigate this, they recommend using the grinder without the blower attachment, accepting a small amount of dead space (approximately 0.35g) in the grinding chamber.
This video is a comprehensive review of the Varia VS6 grinder after six months of use. The reviewers, Benjamin and Michelle Coffee Marker, discuss its design, features, performance in making espresso and filter coffee, and overall value. They highlight both positive aspects and potential drawbacks.
Key design features contributing to the Varia VS6's ease of use and high-quality feel include: its precision-milled aluminum block; a single button and control wheel combo for intuitive operation; the magnet and rubber base providing a stable and quiet placement; and the seamless fit of all components, including the lid and blower attachment (despite the blower's functional drawback). The well-designed dosing cup that fits the 58mm portafilter and minimizes channeling is also highlighted.
