For all of us who wanted to see changes made to the metal mini, the woodvill has them all. Deeper drip cup, door stays on, switch on the side, a bit smaller and much lighter in weight. I have not found on think I dislike about this mod. I LOVE IT. Oh, and the battery stays in place without electrical tape or anything. It's perfect. It appears to have a slightly larger tube so you get a better hit off it. It rocks.
