I got this container as part of the Ascent bundle and have used it mostly to make flour (rye and barley) and breadcrumbs. I can't compare it to a grain mill but it did what looks like a good job to me - the flour came out fine and even. I don't know that I would have splurged on purchasing this if it *didn't* come with the bundle, but glad to have it. Have also used it for smoothie blending when I wanted a smaller container or the 64oz was in the dishwasher.
