The Wispr vaporizer by Oglesby & Butler, the geniuses behind the Iolite, is a brand new portable hand held vaporizer that improves on the Iolite in every way. The designer style appearance is actually a vent system that disperses hot air away from the unit, keeping it cool to the touch. Additionally there is a butane fuel gauge visible on the outside of the vape so you will no longer have to wonder how much butane you have left.Internally the Wispr has improved on the Iolite as well. The new and improved thermodynamic butane catalyst lasts up to three hours before it needs refilling, so you'll save on both time and money for more butane! Available in 5 unique colors.
