hello, I personally have both but just a month in with the auto v2 cig. already sent one battery back (kept burning) sent new one with no hesitation but now my other first battery is acting all up light on light off burn won't burn. but the like the taste and sleekness of the v2 but my manuals seems to hold up i've had them batteries for over a year! wow yeah a year no real cig,yippie! what's your take on this?
