Summary: over-rated Purchased this unit recently and could not be more disappointed. It seems unanimous amongst reviewers that this unit is worth the money but as a person of experience, I respectfully disagree. The experienced user will not appreciate the low-herb-volume of the chamber relative to substantially cheaper units. To be specific, 3 volumes are used with the volcano for every one volume using the VapirRise 2.0. Is not very relaxing to have to refill 3 times to obtain the desired effect. All other facets of the volcano are pleasing
