Do RBT vaporizer's' mouthpieces or body get hot due to normal use?

RBT vaporizers' wood body construction and glass flow path keep all RBT vaporizers surprisingly cool. However, session use on high power can sometimes heat the units up such that the wood body in the heater area can become slightly hot to the touch as well as the glass at the load chamber so care must be exercised when handling these areas. No need to worry about over heating as the chip (on the Zion) contains on-board over-temperature protection. If your unit shuts down due to over temperature just let it cool down and it will be as good as new.
