I've used this for almost two years, but I'm selling it due to a move. The cartridge is not included. This sale includes the main unit, tools, and the box. I believe it's still usable, but it does have some dirt and signs of use. I cleaned it as much as possible, but please understand that it is a used item before considering a purchase. Please feel free to ask any questions in the comments.
