I've owned/used several belt sanders over the last couple of years.  This is one of the best.  Powerful, somewhat heavy but well balanced. Because it is somewhat heavy and powerful, I save this for the tough wood, like oak or cocobolo.  (I have a Bosch with a sanding frame that is awesome for finish or delicate work.) The motor does run hot, as another reviewer noted.  The dust collection bag works darn well for what it is.
