I really like the larger flatter grinding area over the smaller grinder I previously had. My only issue is that its hard to unscrew the top grinder from the next chamber if the top is on. The only thing you have to grip is the time ring of color between the lid and chamber. I just make sure the grinder is completely free of any material, leave the lid off, and then unscrew the grinder. Can be a bit more of a pain with some stickier flower but all in all I do really like it. Does its job well.
