at home i use a vv pass through with both dripper and cartotank (i go back and forth) and a vv mod with cartotank.
at work i keep a ego battery, rda and cartotank.
i have 2 stealth vapes, both under 3.5" or 83mm.
for social i use a regular ego+cartotank, one of my stealths and a very nice mod w/dripper for show.
