I guess I am of the minorities, I started out with one of the KR808-1 kits, I like them because of the feel and similiarities to a real cigarette.
I got the Joye 510 for the same reason. I also wasn't sure if vaping would be for me. After a week I knew it was and got the Riva for the longer battery life. That was the only complaint I had about the 510 - I wanted a battery to last longer on a charge.
