Aspire Mini nautilus and a smok 1100mah vv . This thing vapes great , so much flavor and great throat hit . You can adjust it from tight to wide open air flow . Came with an ego cone and looks great on the battery , not cumbersome at all. Just a little bigger than a kanger aero tank mini ( wife got one and an aspire with her kanger 1100 mah vv ) . Love this thing . Comparison between them , kanger can fine adjust the air flow , the aspire has for settings . Kanger is slimmer but also holds less liquid . The aspire hits a lot like a cartamizer in its vape , nice and thick with lots of flavor , I like it better . Happy vapeing .
