will I be missing out on anything apart from longevity of not having to refill doing this instead of putting a carto in a tank?
My cartos last longer in a tank, and give a much better vape. The taste is better because you're not going from full to dry, full to dry constantly.
Out of a tank, my cartos went from a wet/cooler vape to a hotter/dryer vape all day. With tank- consistent ALL day, and no fear of that bad burned hit.
Then again, I never topped off a carto all day, that would have helped things, but might as well be dripping then.
