The Flux is a simple beast. It's not so much a grinder that utilizes a Mazzer burr as it is a Mazzer burr with a grind chamber screwed onto it. Disassembled, there's nearly nothing to it. The outer burr has a ring of magnets attached to one side and a surprisingly light grind chamber and spindle attached to the other.
