This is in the wrong section.

The erbo is a pipe and belongs in general methods category.

THIS IS NOT A VAPORIZER!!! The whole point of a vape is to reduce the temperature applied to the herb. By just leaving that liquid state, THC becomes unstable and ready to bond chemically. By burning, you convert a LOT of THC into carbon.

The erbo is a gadget in my opinion. It's just a bubbler with an air pump hooked up to it so you take the same hit every time. Predictable yes, vaporizer crazy stoned? nope.
