It is worthless if you need a very fine grind for Turkish or espresso. I thought I would break it before I got anything to grind. I had to take it apart and clean the grinding mechanism of the fine powder because it clogged up before producing 1/16 spoonful. I backed it up a few notches and still had little success. I haven't tried a courser grind yet. If it will at least grind course, within a reasonable amount of time, I will keep to use when traveling with my French Press. Otherwise, it will be thrown away or sold in a rummage sale. Don't waste your money. I gave it two-stars only to be fair since I haven't tried a course grind yet.
