I got the black grinder because it looked slick on DopeBoo and it definitely lived up to my expectations. A nice addition to your arsenal if you regularly enjoy flower.
Santa Cruz nailed it with this grinder. Really solid design that lets me get the most out of my dry herb. A little on the expensive end, but like they say, "You get what you pay for."
I love grinding my dry herb, whether it's for hand-rolled cigarettes or my water pipe, and I've had quite a few different grinders in my time. This, however, is the best. If I ever lose it or something, I'll definitely replace it with the same one.
