So far its fantastic! Very smooth grind. I've only used fine ground grinders my whole life so I chose the coarse ground plate for the brilliant cut, and that really makes a huge difference in lowering both the effort and time it takes. I will see how resistant to gumming up it is in the following months but so far have put quite a few g's of flower in it the past couple days and there's not even a spot of gunk in the grind plate or top.
