Tunkawa sir no offense taken. I go through a 30ml bottle in a day to a day and half (used to avg 15ml's a day, tanks have raised that intake). These kits are by no means for everyone, same with the kr808 kits. If someone prefers battery life and less th will point them to the oem kits, but in all honesty will never advise anyone to buy something I wouldn't vape myself. Had vgo kits before Vapor4Life offered them, didn't like them then, still don't like them now. My review was an honest one from someone who is a truly heavy vaper.
