I am amazed. I have been looking for a good spice grinder. Tonight I was making meatloaf and preparing chicken and ribs. I actually ground up some coffee beans, peppercorns, cinnamon sticks, Coriander seeds I did have to grind these items a bit more than I thought.( Keep in mind this is my first time using a grinder) My first use my spices were a bit chunky and clunky but after some trial and error i was in it and everything can out smooth and consistent. Also although I am not a coffee drinker having fresh roasted coffee beans lends a nice fragrance throughout the house.
