I think all of us were amazed what a huge difference in the ability to quit analogs and the inexpensiveness of the ego systems, compared to the mini's that most of us originally used when quitting analogs...the egos made it much more cheaper and much more effective a way to quit tobacco cigs.....but as bad as most all mini's are , that's whats advertised on TV and seen in convenience stores which caught our eyes, and started most all of us on this new journey and eventually allowed us to quit tobacco cigs....and for many , turned into almost a hobby..
