I got my first eGo type battery about a month ago, an Inferno from volcanoecigs; I ordered just the battery since I already had everything else I needed, including the usb cord; I decided not to get the cone because I preferred the way it looked without, kinda techno without looking like a fancy pen, and I've been very happy with it. The other day I ordered another Inferno for my wife, and I decided to order cones for both this time-wow, what a difference; okay, it looks like a fancy pen with a baby-bottle nipple on it, but I'm getting more and better vapor now, and the sound of the atomizer working is audible but subdued. Something to do with the airflow I think; after all it was designed to be used with the cone. Of course I can't use it with my tank, but I'll be using the cone whenever I'm using carto's from now on.
