When it comes to the Arizer Extreme Q vaporizer, the Q stands for quiet. Arizer released this product in 2010 as a revamp of their earlier Extreme line. The objective was to make their already favorite product better by improving on some of the most critiqued aspects. As with many forced air vaporizers, the sound of the fan can become bothersome over extended use. Arizer has tackled that problem by decreasing the noise created by the internal fan. While they were inside, they also increased the efficiency of vaporization by 50%, creating one of the better-engineered devices out there.
