Spent a 1/2 hour putting it through its paces yesterday. It is an excellent little mill. One nutmeg was transformed into powder in less than 20 secs and I can't wait to try it out on coffee beans. But tried it on garlic with a small chopped onion and it was not successful and neither were a few garlic cloves on their own. However, garlic and ginger, worked well. The storage jars are superb: glass with tough white tops, but I found the mill fiddly: instructions about the location of the blades, jar and rubber ring have to be read carefully - the ring fits in 2 places; only one is right.
