I think that untli/unless you get past the whole " it's got to LOOK like a cigarette", you're likey better off sticking with an ego or something similar.
They're pretty good for what they are...I used one for several months until I started wondering if there wasn't something "more". I tried a few different form factors, models, etc....some were better than others, but none of them
really wowed me with the performance. Then I tried a buddie's GG with an Ody on it....I decided then and there that I didn't really care all that much about the big silver dildo thing.
I got a Stealth, and an Ody, and a bunch of coil building materials. It still frustrates me at times, but that's all due to my own failings in coil construction. When I get it right, it is a fantastic experience. It occurs more and more often too, now that my coil building has gotten better. I still have several smaller e-cigs, but the GG gets the use these days. It is better, plain and simple.
