The folks at iolite have come out with a new portable butane based vaporizer. They aren't exactly cheap, but if they are anything like the past version, they last a long time and work well. This latest version of the portable vaporizer, the WISPR, looks more like a a 1950's gadget and comes in grape red, espresso brown, pistachio green, pumpkin orange, and oyster blue.
Simply fill the WISPR vaporizer up with your favorite herb or tobacco and a bit of butane and you are off to the races. Yours for about $220 here.
