kayfun Lite V2 is my favorite and daily vape. Is it the best? Likely not but it is trouble free and keeps on hittin. Kanger Subtank is defiantly a game changer but at this time it is unproven the test of time. Everyone likes something different and as you work your way along you want better and better as you go along this journey we call vaping. If we did not keep getting more clouds and more power to produce better clouds their would likely be more of us going back to smoking or chewing gum or something. What ever works for an individual is good. We are all different and that is good because it would be a hum drum world if we were all the same. CHEERS!
