I just got my SiD in the mail yesterday, and after waiting forever for the batteries to charge, am vaping away quite happily on it. I like this! Seems to be a smoother vape overall, more flavor, even though I'm running a tank I'd run on my MVP at the same settings? So, what's going on here? Why is this different? Don't get me wrong, I'm not complaining, I'm just curios as to why.
