Mahlkonig E65S gbw (grind by weight) - Matte Black. Lightly used in my coffee shop for 4 months for decaf espresso. No issues whatsoever with this grinder. We pulled 5-10 shots on it per day for those 4 months. I am selling because it has an MSRP value of $2950. It is a fantastic grinder, but slightly overkill for the amount of use we get out of it. I am going to downgrade to a more cost appropriate grinder.
