I bought this before I knew anything about coffee. For not a lot of money more you can get a refurbished burr grinder that will be more consistent and leave less dust. The chamber maid cleaning system didn't do a great job because this pulverizes some of the coffee beans in order to crush the other beans. It doesn't have any way to control how coarse you want the beans except for how long you grind, so only use this for a paper filter drip pot - no espresso or french press.
