What reviewers say about the C40 MK4 Nitro Blade

it grinds coffee like no other, with minimal retention and clumping
I have no reservations about naming this one of the most well-made, cleverly-designed, expertly-crafted gadgets I've ever used
its $300 price tag may make it unattainable for many
Grinding a brittle, hard roast bean to anything finer than about 20 clicks was really hard
