Wicked Roots Vaporizer Commpany stands behind every single herbal vaporizer in our catalog. If there are absolutley any problems feel free to contact Vaporizer Support in our Company Info directory. Wicked Roots is not your fly by night type of vaporizer manufacturer. We know what we built, and we stand behind all our products. All our vaporizers are made with a new ceramic heating technology that has no service life. This means they will last forever vs other aluminum heating elements used in so called "medical grade vaporizers." When you purchase a vaporizer from Wicked Roots be assured we will treat you like family and if there are any problems we are always here to help you. We will be releasing a forum for our family of customers in early 2005, to show that we stand behind our tobacco vaporizers.
