GrimmGreenIndustries Also don't make it too complicated for yourself. Buy an affordable mod with a good battery life that you can live with. I quit using the patch as well but wasn't satisfied...missed the smoking sensation. My first e-cig was a 902 from Modern Vapor and then found that the battery life wasn't good enough so I went to mod similar to the e-go and still use it once in a while. My favorite mod is the super mini from Electronic Cigarettes and E-Liquid - Great Lakes Vapor. I have gone through several mods before this one. Hope this helps!
