This grinder has difficulty in grinding beans on any but the most coarse setting, 5. Regardless of what setting you choose, the setting will shift as you use the handle to turn. I found that the only way to really use this grinder was to initially grind the beans on 5, then regrind them on another setting to get the desired result. I purchased this to grind some coffee beans given to me as a gift, but won't likely ever have need for it again once that bag is gone. Does work, but wouldn't purchase again.
