I just bought a Lavatube look a like from china and no matter what voltage I run it at it still runs very hot to the point that I get a burn taste no matter what. I do not own a ohm meter yet but I am getting one soon. I am just wondering if all VV's do that or if I am doing something wrong. I know that it runs hotter as I go up on the voltage but even at the lowest setting it is still giving me the burn taste and burns the cartomizers really fast. Please let me know what you think is the issue? Thank you so much for any kind of information.
