I've only had this grinder for three weeks, but it sure seems like a winner so far. It is quiet and fast. And I really like that it is compact. Maybe too small for grinding beans for your high volume drip machine, but it sure works great for any variety of small machine. It is easy to judge the grind by the sound. For espresso grind it works quite well. We have a big expensive grinder, but it takes up too much counter space and is a pain to set up, clean, and put away.
