Were You "happy" with just your Pal Mals, or your Kools? Probably so, they did what you wanted, until you either no longer wanted them or had to get rid of them. Of course, we didn't have much of a "real" selection either for the longest time. Then we got teased by flavors for a while, until it became illegal to have flavored cigarettes.
Now, you're in a different world. Now, you can customize your intake, and how the device(s) you use looks, as well as performs, to Your hearts desire. Some will be happy with a simple eGo battery and a clearo. Some need something they can hold on to and swish around like a light sabre. But, in the end, it's your choice!
So, does it matter if it's a simple Blu, Krave or Green Smoke, or eGo VV or a Provari? Not at all!
