The wax chamber is state of the art, seemingly simple, yet complicated to make. Herb-e is concentrate conservative and will use every drop. It is highly recommended that you do not over fill this device. 5 clicks of the button and its on, then press the button and inhale. We suggest gently inhaling. Count to 4 or 5 seconds when using for the best possible results. Also with Herb-e 7, it's discrete and powerful. No big foul smell. Just a hit that is as smooth as cocoa butter. Thank you for purchasing the best and smallest wax vaporizer available today.
