Whilst I'm letting it sit I was just wondering .. I have been using e-cigs for about 2 years now and i have always smoked it by drawing into my mouth and that inhaling the smoke and exhaling. This is the first ecig in that this technique does not give the desired effect for me. It seems like to achieve a decent draw and lots of smoke it needs to be inhaled directly to the lungs. I was just wondering if different models are made q different techniques or if its a personal preference?
