I have left me with buying on other reviews here, but was still skeptical. Perhaps much in advance for the field of application: I drive professionally quite a bit and then smoke tons in the car. However, my wife hates cigarette stench also for our little ones. Therefore, I needed something beyond the normal things that yes rather einparfümieren, transcends. Smoke Ex acts absolutely, if I leave the stuff overnight, no more smells in the car to smoke. A friend of MIR militant Nihctraucherin has been praised for me that I do not smoke in the car :) thousand times better than anything else I've tried. Even the Gemüffel of usneren two dogs going out with it!
