I'm new to the vaping world and this may be a dumb question but... what is the attraction to vv's, provari's or mods? Is the battery life longer than say a 1300mAh X2 or Ego equivalent? Actually that was two questions. I just want to understand what you get from these "upgrades".
Oh I forgot to mention that I use a Volt X2 1300mAh. Long battery life and tons of vapor (to me).
