I really dig Virgin Vapor, although so far I've only tried 4 flavors.
The Best Damn Tobacco chewed up my iClear, but the Hunger of Persephone (Pomegranate) works perfectly, and tastes wonderful.
The BDT juice works perfectly in my Volt mini, and I love the taste. It's just a thick juice, needs a tougher kit. Just got Thrilla in Vanilla today, awesome taste, another thick one though.
I think the stuffs top notch. For me it's more about what i DON'T get with VV: Aspartame, Sucralose, and a wide array of other synthetic flavors and sweeteners. Aspartame and Sucralose are terrible for you, and I haven't gotten a single other eliquid vendor to respond to my questions about whether they use them or not. I'm not too worried about the PG, but at least you can't de-ice a plane with VG...
I'd say as a young VV customer I'd rate them at 5 stars, especially considering they've gotten me my first two orders within 4 days of me clicking submit, from the other side of the country.
Edit: also, I liked the Best Damn Tobacco a lot more after letting it steep with the cap off for a couple days.
