I've been a cartomizer user for the last 1-1/2 years and tried many from Green Smoke, Smoke Tip and many smaller companies finally settling on the Smokeless Image next gen Volt cartomizers which claim the put out 30% more vapor and i love them as they are way better than others i'd tried. That being said i thought i'd try a tank system as so many on here seem to think they're best so i ordered a Vapor King premier starter kit at $129. Very disappointed as vapor output would be hard to match the Green Smoke or Smoke Tip output and not even close to Smokeless Image Volt carts. Anyone that has any information about systems that can match the higher vapor i need i'd appreciate any input. Thanks.
