I have a Vapor Brothers and there isn't much smell there. I blow big clouds of vapor mist, and if someone was in the room at the time I was vaping, I'm sure they could probably smell it. But maybe just a minute or so later, if someone was to walk in, they wouldn't be able to smell a thing. That's the thing, since you are not "smoking" the smell does not linger in the air. I personally think it would be excellent for a college dorm or anywhere else where you want to conceal your baking (hotel, parents house, etc.).
