They didn't know wat ti ss ni stood for and the used normal coils in tc mode.thinking it was ok.
Makes sense. Vaping is just not as easy to do as smoking when all you have to do is take out a smoke, lite a match/lighter, and away you go. With vaping there is more to do, depending, but alot of people that are trying to quit think that it is as easy as when they smoked. They do need instructions on what to do, and the manufacturers are bad about NOT putting good (or in some cases, any) instructions in with some of the products they sell, and TC is more complicated than VV or VW for most everyone when they first get in to it, hence all the TC threads and questions.
