The BUNN G9 2 HD offers great flexibility. Not 'downward facing dog' yoga-style flexibility, rather the twin hoppers make it possible to have Regular and Decaf, or Light Roast and Dark Roast, available for grinding at the flip of a switch. Greet the morning with a 'sun salutation' and the piece of mind that comes from knowing you can change your grind without losing your balance. The BUNN G9 2 HD grinder can really go with the flow!
