Received mine last week and the grinder works like a charm: consistent, light weight, easy to adjust and clean.
Few notes: 1, grind on a flat surface and hold it there, you will get better consistency. 2, you can count the number of threads, if you want to come back to a certain ground size
Enjoy the taste of freshly ground coffee at home any time ceramic mortar has no odor, does not rust. The coarse powder is adjustable simply by turning the knob, also, you can calibrate the amount of ground through the transparent bottle. When not in use, you can store the grinder without the handle. Secure design makes for easier grinding. Easy to clean with disassembled parts, slim design saves space.
