I currently have the ego but and patiently waiting for my Varivolt.
SmokeStik is the only one I have used. I like it, it feels like a cigarette,and I don't smoke anymore!. I would like to try some others.
But e-cigs are an expensive habit; I am spending much more on cartomizers than I did packs of cigarettes.
With that said, I really enjoy vaping!
"What is the best personal vaporizer?"
The one in your hand that keeps you off cigarettes.
That is by far the best answer EVER!
I have both Riva and eGo batts which I love, but I've been looking at mods recently. I want to move up to either a true 3.7 or 5V PV. Still haven't decided, but I've been looking at the Precise and GLV-2's a lot.
I'm with you on the 6 volt comment. You didn't state that you tried a 5 volt mod or a variable volt device. I think you might find you really like this level. If you don't want to put the money into a VV, you might want to look at one of Ken's 5 volt box mods. They do a nice job.
