well I bought a pen style vape two days ago .I spent the first day fiddling around with it ,searching online for how to use ,and getting frustrated and just grabbing the pipe.The second day I decided to try on of the two extra heathing elements that came w/ it .I got it working ,took two puffs in the garage and another walking to the front door ,turned on the tv and saw the most intense ,unbelivably detailed dog bisquit commercial ever ! So vaping definetly exceded my expectations too
