This mill pounds through grain like a champ. There's no going back to my old Corona mill. When I got the mill, it required some minor assembly, basically just connecting the hopper to the rest of the mill, and attaching a hand crank. It took all of 5 minutes with a screwdriver. I removed the rubber washer they use to space the rollers, and used a credit card as a spacer. Setting the mill gap was easy when you get the hang of it- undo a screw, twist an adjustment knob back, stick a credit card in the gap, rotate the knob back until you can *just* pull the card out, screw the screw back in to lock in place, and repeat for the other side. And it only needs to be done once, no constant readjustment like my Corona needs. Time for the crush. I used the hand crank, because I do not have a low-speed, high torque drill that you need to motorize this. Cranking was tougher than on my Corona, probably because the BC crank is much smaller, the gap is smaller, and almost contacts the mill's mounting board. Honestly, the crank seems like an afterthought- this mill *wants* to be motorized. The mill fit perfectly on top of a 2-gallon bucket. I didn't condition my malt at all beforehand, and ran about 11 lbs of pilsner malt through the mill. The crush was *perfect*- while my Corona's crush was uneven, producing a good amount of flour and uncrushed kernels, the BC crushed much more evenly, producing minimal flour and no uncrushed kernels. The malt was nicely crushed, with husks moderately broken up, and endosperms exposed and cracked. My efficiency got a big boost- I got roughly 81% compared to the 63 to 73% I was getting before. My grain absorption also went down about 0.02 gallons/lb, so I ended up with over a quart more wort than I expected. I haven't tasted the finished beer yet, but early samples have been clean and promising. Based on my limited use so far, I definitely recommend this mill. I know several other brewers who own BCs as well, and they have nothing but good things to say about them over the years they have used them.
