I just received my eGo yesterday, and I'm so impressed with this thing using it with my e turbo carto (stardust style) that I honestly don't see any need to get into the world of mods or any higher voltage.
Up until now I was using a RN4081 battery from the mall and it just didn't feel like it was the greatest. It always left me desiring more. Now with two eGo batteries and everything I am completely satisfied.

I was just wondering how many other users have just been satisfied with their eGo kit and don't feel like they need anything more. Happy vaping!
