Nice one! I enjoy this tank alot. Don't throw out the x1 0.2 coil it comes with, they are really good too. Got mine atm at 80 watts and flavour is banging, had it at 100watts for a few days too, but was guzzling juice too quick. One thing I notice with the cerberus though (might be the coils also) is the wicking is quite slow as there is alot of cotton in the coils, so I tend to open and close the top cap every few pulls just to fully saturate the coil and cotton, as I like to chain vape
otherwise its easy to scorch the cotton. That's the only con with the tank IMO, im not sure if all sub ohm tanks are like that but it doesn't bother me too much, but something to watch out for . +1 on the bubble glass, I think it brings it to 5.5ml
