Soak in the high-gloss perfection that the people from Firefly have cooked up for the public this time around: The Firefly 2. The added concentrate functionality is a revelation in both ease and performance. Also included is an app, an industry-standard feature that Firefly has made simple and effective. Firefly 2 is everything that you want in a portable vaporizer. It can even outclass home vapor units, all while being light enough to hold in the palm of your hand.
