Like the title says, has anyone in here who smokes actually used one of those e cigs? Do they actually work well? Is it possible to get one that doesn't emit any kind of smell? Any tips on buying a quality one? I've been doing some research lately, but 90% of the "facts" out there read like marketing hype. Anyone? PS: I don't plan on quitting smoking and don't care of they are just as bad as smoking real cigs. I just travel a lot and looking for a clean nicotine source for my 12 hour plane trips. Thanks.
