I use my KR808D-1 style ecig anywhere I would have had a cigarette - except I don't use it as much as I smoked analogues. At home I tend to vape more often but in smaller 'sessions' and I do it freely. I've contemplated using it at the mall, in a bar, in a restaurant but haven't had the guts to do it yet. And am too shy to ask... I have ninja-vaped more than a few times.
