Detailed Commentary
Lesson learned.... I bought this grinder mainly because of the price (under $50) to start grinding my own beans. Unfortunately I mainly use an espresso machine and have used the Lavazza Rossa ground coffee which worked well, but I wanted to grind my own. I bought this grinder, used in on the finest setting and the coffee was much coarsely ground as compared to the ground coffee I was buying. End result was the worst espresso I have ever made. I am now in the market for a "Rocky" grinder. mistake
