The Box performance is much better than any other vaporizer in its class due to the following four factors:
1) The Box generates vapor only when needed -- it does not waste any vapor by staying hot between draws or by continuing to cook the load after you have had enough. Loaded material can continue to be cycled over any extended period of time, delivering vapor when you want it without ever having to wait. Conscious user technique with the battery can ensure that there is zero lost vapor every time.
2) The Box makes careful use of infra-red (IR) characteristics in its design. IR vaporizers (although very uncommon and very expensive) tend to be fairly good since they have overall heat distribution characteristics similar to pure convection designs for smaller loads. The Box uses only and exactly as much heat energy as is needed for vaporization (the Box is easily one of the world's most energy-efficient vaporizers).
3) The Box incorporates several vapor channel flow features to ensure the absolute minimum vapor condensation. Convection vaporizers necessarily need to use significantly more heat energy to operate efficiently -- heat which must be removed from the vapor prior to ingestion. Any surfaces, piping, or water chambers used to cool the vapor are also condensation sites. Condensed vapor is lost vapor and that means that a big pipe overall is less efficient. Any parts that require occasional cleaning also indicate a significant volume of previously lost vapor. Used natively (without the optional stems), the Box rarely requires any cleaning since it delivers the vapor directly to you -- without converting some of it into black gunk along the way.
4) The closed chamber allows for the simplest and most reliable form of mechanical stirring possible: shaking. By shaking the Box between draws, the previously ground load can be evenly re-mixed to ensure much more even heating. The clear lid also allows for immediate inspection to determine both the effectiveness of the stirring and the degree of completion. In this way, good user technique can result in excellent overall performance and efficiency.
In summary, in-house lab testing has shown the Launch Box to be nearly as efficient as the best portable vapes (when used correctly), and noticeably better than most. Dollar for dollar, the Box delivers more vapor in more locations more naturally than any other.
