ABSOLUTELY INCREDIBLE! As an espresso enthusiast, I was tired of electric grinders that heated up the beans and ruined the flavour. The KernelTuni has completely transformed my mornings. The 50-step adjustment is incredibly precise, and grinding 20g of beans feels effortless. It's solid, stunning, and cleans in seconds. Highly recommended!
