What kind do you guys use, if any?
I have a magnetic one with the teeth (as opposed to the needles). It worked well for about 6 months but now it gets dirty (to the point it doesn't grind at all) after a few uses and when it is clean enough to work it always seems to magically eat up the bud. I put in like a whole bud and when I pour it out it seems so little.
Thinking of picking up a new one...
