Hello there! New to vaping and forum, bought my premium starter kit from O2 vapors and want to upgrade now. I bought one of their clearomizers, and I know they are suppose to be used with a passthrough. What is the main advantage other than higher capacity? (280 mah vs. 900 mah). On their website, it says I can use either one but the button (I have a manual) is too close to the actual clearomizer to use comfortably.
