If you want to try getting into the gg mods, the ggtb is a great way to start. simple, elegant, easy to use and best of all not a bank breaker. it gives you the style without all the hassle. i won one in a contest and have to say that it is excellent. I usually vape at 3.7v with a lr cart, but this has opened up my vaping options by letting me into the 6 and even 7.2v range. Definately a lot of options and functionality.
