Query: Does the job so far

We bought two of these for our two SUVs (Ford Escape and Toyota Highlander). We plugged those in the cigartte lighter sockets. Fortunately, our cigerette lighters are not powered when the engine is turned off. So, we can leave the units always plugged in. The ionizers blink a green light at your face when they shoot the ions, and that can be quite annoying. So far (about two weeks) both units are working well, and eliminating odor. In my car, I had sprayed some old de-odorizers and that had resulted in a bad stink. After plugging in the ionizer, that smell is gone :-) Now, I do not worry about giving rides to others in my car, and it is a good thing.
