The outside frame for this Vaporizer is made of fine birch and solid alder wood and has Black or Brown colors. It also features a digital display that allows the user to adjust the vaporizing temperature with maximum efficiency and accuracy. This is a great cheaper alternative vaporizer to many other digital vaporizers. Each unit comes with a standard 3 year warranty that covers any defect associated with the heating element. This is a great unit for anyone that’s a first-timer to vaporizing and looking for a good “starter vaporizer” model.
