Great grinder for espresso, but would prefer it not to have a doser--personal preference.
Positive Product Points
Excellent, uniform, fine espresso grind with easily adjusted grind control, adjustable in very small steps. Excellent flavored espresso. Strong motor, heavy duty construction, interesting combination of flat and conical grinders. Great for mass loading and grinding as much as you need into the doser.
Negative Product Points
Grinds loudly and very slowly compared to my Mazzer Major. Probably not a good grinder for drip coffee, and frankly, I don't like the doser, but then, I don't like any dosers. Also not good for grinding measured amounts of beans, they bounce around forever at the end. I mass load the hopper and grind what I need, counting the seconds to produce the amount of ground coffee I require, and ratchet the ground coffee out of the doser, emptying it into a glass. At least that process is fairly predictable. Not an easy method, though. I wish the grinder didn't have a doser.
This is an excellent espresso grinder that in spite of features that bug me, I still like it for its excellent overall performance as a grinder. It's at least the equal in quality grinding as the massive Mazzer Major I own, perhaps a little better, though slower by twice or more. Does a great job grinding finely. Might make great Turkish coffee, but I've never tried it for that. The slow speed does make it easy to time, though. It also fits under a standard kitchen cabinet on the counter. It's attractive in a modern way, heavy, powerful, and grinds with great precision. The little knob you turn to adjust the grind makes minor adjustments in grind easy to make and to return to a previous setting. But don't buy it for bulk grinding or going back and forth between espresso, drip, and other grinds. It's really made for espresso.
Chris Coffee folks really helped me choose my grinder. These folks are not only well informed, they're also helpful and want the buyer to get the most satisfying products. I'm sure there are other great places to buy from, but I can't imagine anyone doing it better.
