The point of vaping is to have a smooth experience that gets the job done but is not too hot. Different flowers and herbs will bake differently and user preferences widely vary from heavy vapor to very light - so it is important to adjust temperature settings accordingly. On this front, the options are to choose a vaporizer pen that has pre-set temperature settings to choose from, or a vape that allows the adjustment of the temperature by a single degree. Both options are great, but if you really like to fine tune the vaping experience, make sure to have full temperature control.
