So now we have the v8-t10 coil which can fire up to 300 watts. (Haven't tried it that high, never will) we also have the gold blue and gunmetal versions of the tfv8, which I just bought a gold one for a good price. Then I go to the smok website and they just came out with red, green, and rainbow! LOL they're killing the vape game and me at the same time. I wish I had unlimited money for all these colors
