I have a similar problem with Volcano e-cigs, no vapor and no matter what I do, I keep getting juice in my mouth, it burns my lips and tongue, and I get a nasty sore throat. So I tried the E9 from e-cig.com, good vapor, but after about 20 puffs the polyfill in the cartomizer starts burning. I don't care if the battery life is short, I can always carry spares, but the burning carto is a real bummer and is pretty discouraging, especially when the carts are suppose to last about a pack of cigs and ends up lasting about 2 cigs. Feeling disappointed and scammed.
