I didn't buy this tank from here as it was not available on this site at the time of my purchase. I love this tank! Smooth warm flavorful vape from the 0.4 ohm coils at 52-55 watts. No leaking, none! I carry my mod/tank in my pants or vest pocket all day at work & am constantly on the move (no desk job here) & in the 2 weeks I have had it has not leaked at all. Still using the original coils too after 2 weeks & they are on point. Smok got it right with this one. Easy top fill with no cap to keep track of, just press down, twist open & fill it up.
