So, what's up peeps as usual I'm looking for hardware and the TfV4 by Smok seems like it's earned its way to be a new addition. But, I would like to get some feed back on the longevity of the coils, they crave high watts and since in the past pre built coils don't really last long at all for me, i.e. a few days or more (Atlantis days, maganus maybe a week at most) I dig and vape high Vg, how long are they holding up to high watts? I will get the dual coil rba for as well. Any thought and opinions on it would be appreciated, thanks! ( I may hold out for the black one, Merica')
