lol no it's not an air freshener. a cable attaches to the bottom of it which has two electrodes on the other end. the electrodes go into a rubber piece that fits into a plastic clip, and the clips attach to your earlobes. the rubber part with the electrode gets pressed against the back of the jaw. there are other ces devices too which use many frequencies intended to put a person into different brain wave states. i have not tried those. it's worth it to note that there are a few different technologies which apply an electrical current to the head. there is of course ect, the purpose of which is to induce seizures. there is also transcranial direct current stimulation, which i do not trust. there is also pemf for the cranium, which i also do not trust. ces appears to be the safest.
