I love the idea of this and it makes delicious freshly ground coffee. However, A few things are confusing to me. First, the instructions are to empty the hopper before removing the bottom. There’s really no way to do this without turning the entire machine upside down since the hopper is not removable. Second, filling the hopper is tricky without spilling beans because the grinder is blocking the opening. And lastly, the measurements aren’t accurate. You always get 2 more ounces of coffee than the amount you selected (not necessarily a bad thing, but strange )
