TIRIRS 3 Inch Large Spice Grinder - Purple (12 Pack) | Perfect for Grinding Herbs, Spices, and Coffee Beans | Ideal for Kitchens, Restaurants, and Home Chefs

This grinder is good, and it does what it's supposed to do. I find it works really well on drier herb, but it also isn't bad on stickier herb either. The design makes it easy to grind, but this thing can get a little jammed up if you don't keep it clean, or you really pack it full. Otherwise it works fine. I do wish it would collect more keef but that's a minor issue for me. Overall for the price I couldn't pass it up.
