Congrats on your purchase!! I quit a 40 year habit with my eGo. It is a really good, reliable pv.
However, I hate to tell you this, but it is unlikely to be your last pv purchase.You won't need to, the eGo is terrific, but, you might end up loving the idea of variable voltage...you might want something you fill once and don't worry about for a day or two (REO Grand)...or you might just end up falling in love with the the look of a beautiful hand-crafted mod. Fortunately, you will have all of that money you are not spending on cigarettes.
I know of one seasoned vaper who's finally decided that size does actually matter and stepped back down to a smaller one.. LOL!
