i've used a couple vaporizers. My friend had the wooden box kind that had a heating element in which you place the tube on to and it vaporizes the weed. I think thats in the same style as the vapor brothers. Also tried one that was basically a glass bowl that sat on top of a column with a metal bowl on the inside for the weed and you just turned it on and the glass bowl would fill with vapors. Also i made a light bulb vape but it didn't work very well. I'm thinking of getting one from vapor brothers those seem to be really good.
