I just got an 808 last night, and there's something odd about it. When I push the button and take a drag, it's warm. The vapor is warm when I breathe it in, instead of sort of cool or at least room temperature or something like with everything else I have. It's actually really pretty warm, not hot or anything, but warm enough to make me question it. Is this normal, or did I just get a 'special' one?
