The Rocky is the most durable coffee bean grinder available in its price range. It is extremely well made and we highly recommend it for home use and light commercial use. It is a dosing grinder, which makes it especially suited for use with an espresso machine. Although, it would have no problem grinding fine or coarse enough for any type of coffee/espresso machine you might have. The forks that are designed to hold your espresso machine portafilter in place are removable so that you may use any receptacle you want to catch the coffee. The Rocky is the grinder of choice for the finicky home barista due to its quality of grind and durability. Please note that most grinders are tested at the manufacturer and coffee grounds may be found in the grinder as a result. All machines sold are new unless otherwise clearly stated.
