GGTS has lots and lots of fans. I have had two, and, for me, the button placement is problematic. In fact, the button placement is why I opted not to get the EA mod. I also don't like the fact that, unless I can find a stealth cap (a nearly impossible task), I can't screw any of my 510 genesis atomizers on without what seems an unsafe collection of adapters. So, while I know I'm in the minority, the GG is not for me. My experience, my opinion. Please don't flame me for it.
