A few days ago I got my Barley Crusher from the Brown Truck guy. I used it for the first time yesterday. It worked like a champ right out of the box. I put a heavy duty 1/2 drive drill on it and went to town. I normally get 64% efficiency when the LHBS dude crushes my malt. Yesterday I got 81% on the factory direct setting. This may be the best investment I've made since I built my MLT.
