Thanks for the compliments!
I wouldn't say it is superior. I made it because of a thread I read here recently regarding using a soldering iron to make a vaporizer.
People seemed to disagree as to it's effectiveness, so I built one!
It definitely vaporizes the spice. The vapor floats to the top then drop down the sides as it cools. The "draw tube" is on the bottom and the fresh air supply is a glass tube that sticks up near the bowl.
I just wait for it to fill up enough so as not to get hit with the spice to slowly.
I keep an eye on the spice and adjust the temp as needed.
I think this would be best used for changa, and for passing it around in a group type setting.
Very cheap to make, easy to clean and disassemble
