This grinder is a big step up from a whirly-blade. It's adequate for drip brewing.
Negative Product Points
The Braun KM30 generates a lot of coffee dust, which results in a more bitter cup. Depending on the bean, I could rarely tolerate press pot coffee ground with this machine without adding sweetener to the cup, and the last two to three ounces in a 10 ounce cup would be undrinkable sludge.
This grinder is also very loud, which means that since I'm the earliest riser in the house, I had to grind my morning brew the night before to avoid waking everyone else. When grinding in the evening, any conversation taking place in the kitchen would have to pause while the Braun was in operation.
I bought this grinder as a step up from the whirly-blade. It improved the flaver of my drip coffee considerably, but I'd often go back to the bean-banger when grinding for press post because of the dust (and resulting bitterness and sludge) that the Braun generated.
Considering the price, I can't complain about the mechanics of the machine: it held up through several years of daily use, until the burrs finally wore out and the chamber for the grounds developed a crack after one-too-many times through the dishwasher. The plastic housing has a simple, clean design as far as esthetics goes, but access to the burrs for cleaning is awkward. The delivery chute tends to gum up with compacted dust unless brushed out after every use, for which I found using an old toohbrush much more effective than the blade-like tool at the end of the supplyed scoop.
I was happy with this grinder for as long as it lasted. Now that I've replaced it with a Solis Maestro, I see (taste) what I've been missing.
I bought this off the shelf at Meijers. There was nothing note-worthy about the experiance.
