I was considering to buy plexus coils, hoping they would do better than the 1,6 and 0,8 coils, but reading the comments here, that probably will not solve my issues. In contrast to what I read in many posts in this thread, my experience with the zenith tank has been very, very dissappointing. The coils last 3 days max. Worst cases 24 hours, like today. I vape 90% VG and have never had problems with it using Kanger pro- and aero tanks. I chain-vape low power, 6 W at 1,6 ohms and 8 W at 0,8 ohms. Anyone the same issue or ideas?
