I really like my grinder but I have a few small problems. One of them, the pollen catcher at the bottom, gets almost nothing. I know some people like it, but I love using every bit of my herb and its by-products. Grass particles also get stuck around the metal bolts at the top of the mill. The kit comes with a small brush, but not everything works. In general, I've had both better and much worse. This is pretty neutral to me.
