I am trying to figure out if maybe I just got a dud or what but I wanted to share what I have noticed so far with my BVC coils. The 1.8 coil that came installed on my mini was flawless and the vapor and flavor production was great and lasted around 2 weeks before I finally put a new one. I bought a 5 pack of the 1.6 because the b&m did not have the 1.8 I noticed after only using the 1.6 for a few days I am getting this slight and very very slight burnt taste. I vaped it the rest of the day which was yesterday and popped a new 1.6 in earlier today and the same thing is happening it's just a VERY slight burnt taste. I am running it at around 9 watts 4.1 volts .... Anyone else or is it just me?
