Very hip and cool looking vaporizer, made of stainless steel. For those who like the purest flavor. This vaporizer has a digital temperature control, LCD screen digital read out and adjustable airflow. This Digit Vaporzier heatens the herbs and releases their vapor into a large polythene ‘balloon’. The ‘balloon’ has a valve, so you can pass it on after taking a hit. Each ‘balloon’ will provide about 4-6 hits depending on your lung capacity.More information at: http://www.azarius.net/ The study did not, however, rule out the possibility that waterpipes could have other benefits, such as filtering out harmful gases such as carbon monoxide
