I want to get a kit that my wife and I will both like and she is not as interested in diving into mods and so forth as I am so for starters, I am considering a kr808 type kit. From what I've read it appears to me Smokeless Image Volt and Halo are two of the most highly regarded starter brands. Any reason to choose one over the other? Better battery life, better tasting cartos, better vaping experience, better customer service, easier to refill - what are your opinions?
