Not much info, Use ONLY the upgraded Kanger coils, the ones you cant see the wick. The old style fail quickly in comparison for me. I have had them fail immediately or only last a few days. My wife is still on her original coil in her Protank 3 but she is a light hitter compared to my almost fiendish
vaping. I would also suggest getting a VV battery like an Vision Spinner.
I have a few eGo-T batts and they only come out in an emergency.
