This grinder is a perfect machine. It has a strong motor, full sized grinding blades, a large hopper, a sturdy dispenser unit and is very quiet. Buy one with confidence.
Negative Product Points
Hard to come up with any. The price is quite steep if you buy one new. And it will definitely be an overkill for anyone who is not trying to achive "espresso-nirvana".
So I owned a Solis 166 grinder before the Mazzer. This was a perfectly adequate grinder for most home coffee enthusiasts. Nevertheless, some (minor) shortcomings of the solis (slow, loud, plasticky appearance, inconsistent grind, static buildup...) soon resulted in an unbearable rush of upgrade lust. So when I saw one Mazzer available 2nd hand, I went for it and never looked back. It is not only that the machine is very sturdy and would be perfect for most commercial environments as well, it is the little details that I still admire. If you wnt to change the beans, just close a latch at the bottom of the hopper, remove hopper with beans, open latch to release beans to whatever containment, attach hopper again, and fill in new beans. The timer knob lets you grind a predetermined amount of coffee (timer model only!). The dispenser is adjustable. The grind settings are stepless and the grind is very consistent. I could go on and on, but... just be assured that even as a new product, the price is justified. It will be the last grinder you need in your life.
