The Volcano Classic herbal vaporizer is a premium table top vaporizer that uses balloon inflation for vaporizing. The Volcano Classic is the non-digital version of the Volcano Digit, so there is no LED display, but it does not sacrifice vapor quality what so ever. The Volcano Classic instead uses a temperature knob to set your desired temperature. Also the Volcano's study aluminum design makes it perfect for those vaporizing often. Don't have the extra cash for the digital model? Well no worries, the Volcano Classic is still among the best vaporizers available.
