TheGrinch--This is a very personal thing. Is how it looks important? Battery life? Visible vapor production? Flavour? Convenience? Cost?
Most people using e-cigs for the first time want something similar to a cigarette. Most popular 3 peice model at this size is the Joye 510. Battery life for the average user will be about 2-4 hours. The cartridge holds about 6 cigarettes worth of liquid. For larger cartridges, look at the 801/penstyle model with a larger atomizer, the cartridge holds about 10 cigarettes worth of liquid. For longer battery life, look at the ‘mod’ style
devices. For an easy to use model, look at the 2-part try the KR808D-1 or Greencig.
Look for feedback on the forums before making a decision.
