I also started with Safecig, and then I bought a KGO and am very happy with it. I now also have the Provari V2 which is awesome. But I still use the KGO when I go out because I don't want to take my Provari out of the house (afraid of dropping it). I use the Vision eGo CE4+ Clearomizer DV Edition (newest ones) that I get from Discount Vapers. I got my KGO from Virgin Vapors for around $40. Virgin Vapors also has the best juice IMO.
You got to take that Provari with you.... It wants to ride in the car... Mine goes everywhere with me... You know what is great to carry it in? The small felt bags SuperT sells for $1.79... There work perfect with a Provari... The top of the drip tip is the only thing exposed.... Dont even need to remove it from the bag to fire............
