Reviews right here on this site by the "Experts" pretty well cinch it for me and I prefer the KR808D-1's . It seems to rank in the top 3 styles. Good battery size, and power, good carto's that hold a substantial amount of juice. No need for refilling, making them simple (yet I do refill with little effort), Substantial vapor.
We might have some issues with the proper carto or fluids, and try to get optimum performance out of em, but the "Format" is a GREAT setup !
I'm not into mods or monster sized things that will scare women and children. I want something the size and feel of the real thing. I'm replacing cigs and want the same experience (or as close as possible) and that doesn't include dripping filling or all the other mess that comes with it. Yeah, I fill carto's and boil out old ones, and to me it's a pain in the .... If it wasn't for the cost savings (and ability to choose a specific flavor using Johnson Creek) I wouldn't consider bothering with the process.
So the KR808D-1 works for me.
