The Firefly 2 uses convection-style heating to produce one of the best quality vapors available on any of the portable vaporizers. It vaporizes loose-leaf and concentrates, heats in seconds, and delivers a consistently smooth, superb tasting vapor. It’s 55% lighter and 33% smaller than Firefly 1, with customizable temperature settings, an efficient fast-charge battery (approximately 45 minutes), and delightful ease of use. The magnetic fitting lid and borosilicate glass vapor path make loading and cleaning a breeze. The Firefly offers a 2-year limited warranty.
