I have a Dovpo e-lvt with a kanger sub mini tank. I have it set around 25.5 don't know too much about all this. I'm trying to get great taste and my 1st 1-2 hits are great then my next one feels warm and looses flavor unless I let it sit for 2-3 min. The lady at store said I need new mod that will handle Hercules tank. Why won't mine work? I really want to get this vape down totally lost on sub oms and temp. Please help. What should I do. Want the best taste don't care about clouds. Can my Dovpo work out or do I need to shell out more $.
