Hello all.. What a great forum, so much info.. perhaps too much for my newbie, just quit smoking brain to handle. Anyway, I went to ecigs full time about 1 month ago, and I am loving it! Currently I am using green smoke and V2, they are ok, but as I have read on this forum there is a better way. I have been reading this forum for hours and have decided an EGO is for me. I will be bringing it to work and need to keep whatever I use in my pocket. Now for some questions.. Which model should I buy? Should I get a tank model? If I use a tank which is least likely to leak? Can I use cartridges? And if so can I bring a spare with me? What else should I buy with my new EGO? Any suggestions and/or advice is greatly appreciated. Thanks!
