This is the main unit and the instruction manual. I've been using it in my car since I bought it, so it's slightly sun-faded, but there are no operational issues. The main unit has been lightly cleaned. I don't have any pets, and I don't smoke. This is a used item, so please refrain from bidding if you are sensitive to such things. I am also selling a genuine 【replacement ion generation unit】, so please consider using the "bundle purchase" option.
