So I'm not an expert but when I finally stopped using kanger tech junk all my vapor problems went away, no more dry harsh burnt hits all the time. I believe the set up and silica in kanger stuff leads to vapers tongue and hot juice spitting on the tongue. As soon as I switched to rda with cotton and even bvc with aspire all that went away. I've never been happier vaping since I left kanger in the dust, although I'm curious to try their cotton coils. My 2cents anyway, could be wrong but yea give it a try with something besides kanger dual coil silica wick set up and see if that helps.
