vaporizers like that only vaporize the leaf material that touches the element.. (basically, you get a lot of burning potential and not all the THC is vaporized unless you stir it with something..) It's conduction, not convection. A convection vaporizer draws hot air through the material, vaporizing all the surface arera of the leaf, but not burning. Convection is ALWAYS better.

Look into the Vaporbrothers, the Vapordoc, or.. my personal favorite...
