Update for EG1 v2
Assorted beans and roasts produce different particle distribution characteristics when ground at different speeds. All of the power and brains of the EG-1 v2 are neatly engineered into the base, with on/off and RPM control right at your fingertips. The 45° angle of the crisp LED readout allows adjustment to the nearest 10 RPMs, with a range from 500~1800 RPM. The EG1 is PIDed to adjust the power to the motor to grind as close as possible to the set RPM, regardless of the bean. The grinder also goes into sleep mode when sitting unused, dimming the LEDs and reducing power consumption to nil. Adjusting the RPM or just hitting the GO button wakes it up so you can get your coffee grind started immediately.
