We no longer recommend the Vapordoc vaporizer and instead suggest you go with the original vaporbrothers box vaporizer instead.
The Vapor Doc works just like the Vapor Brothers Vaporizer. However the Vapor Doc has an on/off switch which allows you to set the temperature knob to your favorite setting and leave it there between uses.
