This 'Black Leaf' 'Titan' Vaporizer is intended for use with dry herbs only. It doesn't burn your herbs due to the closed heating chamber which sits in a stable metal case. The multifunction power button also serves for regulating the temperature. The LED display indicates the temperature with the colours red, green and blue. Automatic shut-off after 10min. without use. Receptacle for charging with USB cable via computer or power supply.
