I'm really looking forward to the V4! In the
kayfun Addicts group there is a LOT of good info about it and I'm stoked! You can use it as a dripper OR an atomizer, there'll be a sub-ohm kit and a standard kit (probably a set of peek insulators and set of derlin insulators). From what I'm seeing this will be a game changer. For now I'll be happy with my KFL, but as of Dec 6th the V4 will be released O.O
