This grinder works flawlessly on medium to fine grinds.
Negative Product Points
The dial (# cups) is a timer.. not very accurate
Detailed Commentary
I bought this grinder a few months back to replace my mom's 50 year old KitchenAid burr grinder. I really hate the idea of chopping up beans with blades, so I searched for a burr grinder. The Capresso floated to the top of my survey based on price/performance. So far, its worked flawlessly on medium to fine grinds. The instructions strongly recommend cleaning the burrs every grind, but I'm much too lazy for that. So far, it's not clogged. The hopper is large enough for my modest needs, although attaching the hopper to the body of the grinder is a little dicey. The grind container is made of plastic, and so grinds do tend to stick because of static electricity. This isn't a serious problem. It has a dial to indicate number of cups to grind. it actually is just a timer, and actual output varies with coarseness of grind selected. It's a fairly attractive unit, so I have no problem leaving it out on the kitchen counter.
