I have heard that the vapezilla is the only vape that runs with or can even out-do the volcano.

Diffusion was one of your questions. the tube from the vape zilla can have a glass on glass male bong piece replaced with the mouth piece and slipped into the female part of a bong downstem. the glass on glass amkes sure that it all stays in place and airtight. no need to worry about breaking anything as the vapezilla sits flat on a desk and so does the bong. i believe the vapezilla is hands free, and of course a bong could be hands free too :thumbsup:
