The Comandante C40 is a great hand grinder. I was an early adopter, purchasing this grinder over five years ago, when the first shipment came into Australia. There have since been two revisions of the Comandante C40 - and you can purchase the Mk III version here.
This grinder is definitely not an entry level piece of equipment. The grind consistency is quality - and I believe the grinds from this grinder make filter brews comparable to when I'm using my EK-43.
