I smoked for 20 years !! felling helpless in trying to quit and noting working I started ecigs 2 years ago. From that first day I have never had another real cig . I use a mechanical mod and several rebuildable atomizers . Having the ability to pick what I want to use has help me stay off cigs .. I have tried gums, patchs ,cold turkey .nothing worked . My health is better my family is happy and my life is all around better . Thank you . Matt Thompson
