You wouldn't think, after that last post, that I would have more to say, but here goes. A friend, who smokes, was in my car and said he actually likes the smell of the ozone. He uses Sharper Image ionizers and says that the smell is exactly the same from that unit. So if you want a preview of what the Cloaker smells like get yourself down to a Sharper Image store and have a sniff. I have no experience with the SI unit so cannot vouch for it's effectiveness.
