Another very efficient vaporizer is the Myrtalzap (MZ). The Myrtalzaps are made from a solid piece of very hard Myrtalwood, and will last a long time. The temperature is set and not adjustable. The set temp never gave me a problem getting thick vapor clouds, and you dont have to hunt around for the correct temp. It just keeps things simpler. The MZ is another high quality log type vape that works with as little as 0.025g of herb. I'm getting about 5 good hits from a single stem full (0.25g). The 5 hits are plenty good enough to keep me happy for about 4 hours. :420thought:
