Seems like it misses a looooot of nodes, and spends more time fighting mobs than actually mining. It's free so I won't complain too much, but it just seems odd that I'll watch it for it for a bit and watch it run past 4 or 5 nodes, fighting mobs along the way, and then finally grabbing one. I haven't been watching ti closely so I'll keep an eye on it more and see if it's just a fluke at the moment or my settings or something.
