Has anyone used these? The Csonkas and the like. How long does it take to get rid of odors, smoke etc. How well do they work. I want to be sure of these things before I drop $300 on one of them. Thanks guys.

BTW this is a great board. I'm used to the Yahoo stock boards where people haven't taken their meds 🙂
