Ego CC is merely the "kit" with the CC clearomizer + a 1000mah Ego Upgrade Battery. (i.e., 2 settings). I personally would not bother with the CC clearomizer, as it uses type A atties.
Just get a Joyetech twist or a fixed 3.7v evod battery instead.
As for the inhale thing, I used to inhale. Now I just puff and blow out, or sometimes do the mouth thru nose thing. Not sure I want flavorings, etc. to go deeply into my lungs.
