I've been vaping for a month now, I smoked a pack of cigs a day. I purchased Green Smoke with pre filled cartridges (menthol) as my first e-cig. I really like them but they are pricey. I came upon this forum and started reading everything. Great info! I was getting overwhelmed with all of the info and different e-cigs out there. I felt I must be missing something as no one really recommended prefilled carts. So I ordered the halo g6 and I didn't care for it. Too hard of a pull and I didn't like the flavors. Now I have a v2 on the way with various accessories. I have spent hundreds. I really like GreenSmoke but I wonder if I'm not getting the best e-cig experience. If I decide to upgrade would I be looking for a better battery, more vapor? I really would like to quit smoking completely. Also I still have cravings. I purchased the 18nic if I go to 24 nic do I just vape less? I usually vape 2 carts a day of 18nic. Thanks for any advice.
