Precise grind control: Infinite adjustment knob lets you dial in the exact coarseness you want, from very fine to coarse. Ideal when you need consistent particle size for better extraction and a more predictable cup. Observe beans while grinding: The transparent bean hopper makes it easy to monitor bean level and watch the grind process so you stop when you reach the amount or consistency you want. Stable, consistent performance: Dual bearings hold the burr assembly concentric and balanced. This reduces wobble and uneven wear so each grind is more uniform and repeatable.
