As I've seen in other reviews, this arrived with a couple of dents and a scratched screen. As disappointing as those things are, for the price I will ignore the cosmetics.It worked as it should as far as I can tell and will update my review next spring after a winters use in the shop.UPDATE: After only a month of continual use, roughly 10-12 hours per day, the heat output dropped significantly.The unit was tuned well enough with no smoke emitting during startup or shutdown, I'm assuming it's the fuel pump as the fuel consumption also decreased with no changes to the settings.
