I have a couple of Scent Blocker products, and one Scent Lok product, so I am not pushing Sent Lok or carbon by any means. It is really only an extra "can't hurt" for me. I won't spend big bucks on the stuff, but if I get it cheap, why not?
Respect - don't take it, unless you are willing to give it.
Responsibility - don't give it, unless you are willing to take it.
