After using the mk for a few weeks, I finally got the time to pull it apart for a decent cleaning. It was surprisingly fairly clean, the burrs are in pretty good shape, the grind produces clear as glass flavors. If you haven't noticed, I have decided I love this grinder.
Two very accessible screws on the front and the burr is out. The plastic hopper isn't really necessary for my very non-commercial use, so I saved a little time on reassembly.
