Disappointed in both Aspire and Kanger tank systems. New aspire coils taste good, but no throat hit on 50 50 juice. New Kanger coils only last 4 days if even, before the burnt hits start! We put a man on the moon, but can't get this right? Not interested in building attys! I want an analog right now, and have been all vape for 6 years. Your thoughts please. Of course I won't go back, but a bit frustrated.
