Ollygrin vs Circle JOY
Power Source
The Ollygrin is an electric grinder powered by a gear reduction motor that creates a slow grinding action. This design reduces heat from friction, which helps keep the flavor and aroma of your beans intact. You simply turn it on and let the machine do the work. In contrast, the Circle JOY is a manual grinder. It relies on your hand turning an extended handle to grind beans. This requires physical effort but offers a quiet operation that does not disturb others. You can use it in offices or early mornings without noise. The choice depends on whether you prefer automatic convenience or manual control.
Grind Settings
The Circle JOY offers 40 external grind settings. These adjustments are made externally, allowing you to fine-tune the size without touching the burrs or grounds. This makes changes faster and cleaner. The Ollygrin provides 30 precise grind settings. You select the size using a unique rotary button that also controls the cup output from 2 to 12 cups.

It weighs 4.41 pounds and measures 5.4 by 7 by 12.9 inches. This size and weight make it stationary. It is not designed to be carried around.
