I ordered the 18th, and just came home and saw it on my doorstep.. in a medium sized priority mail box.. so that's pretty good fulfillment time . It's pretty easy to assemble. Smells of machine oil, so I think I might just run a pound through first and throw it away. as far as the adjustments go you can go from interlocking ie turning one wheel turns the other to what looks to be an 1/8 or a 1/6 of an inch wide.. The quality of the knurling though I'm not as impressed by, one of the rollers looks like it has smushed points in areas. I don't know if that will help the grain get pulled though or result in an inconsistent crush.. having not bought a grain mill before.. but it looks pretty good and I'm sure it's way better than a corona.
