Doesn't get hot, and no smoke! Includes: Main unit, 1 cartridge, 2 AAA batteries, hanging hook I received this item as a gift, but I'm selling it because I don't need it. The photos show everything included, so please check the contents and understand (that there may be some age-related deterioration of the outer box due to storage). Also, since it's new, I haven't confirmed its operation, so please consider that as well when purchasing.
