I dont like them.They kill the battery to early.If you have a V2 stay with the Blank carts untill they fix it.You do get full flavor.I can run one or two carts 8hrs on a V2 long batt,but V2 LiquiMax Blanks only last me 3 hrs tops then i have to break out another batt.They do work good on Mistic batt for a light vape.
