Starter kits are just that... something to get you started (two batteries, two tanks/clearomizers, charger, etc.). Some people are happy using a starter-kit or some variation of a starter kit forever, but many of us evolve to better equipment and relegate the starter kits to back-ups or pay them forward to new vapers. Personally, I've only bought ONE starter kit for myself, and passed that along to a new vaper within a few months. I've also purchased components (and received several freebies from contests or friends) to make eight additional starter kits to give away to new vapers over the past year.
