I bought my Elev8r on sale from another retailer as a lark. It seemed like a neat setup and the price was right. Boy am I glad I grabbed this little vape. This is the cleanest, most all'glass airpath that I've seen and the heat is almost pure convection, capable of handling concentrates or flower with ease. Compared to my Sticky Bricks, Dynavaps, and other butane powered vaporizers that I've seen, this is not the best for taking out of the house, nor is it the easiest, or best to use. But it's really good. Like, really, really good. And the instructional video that 7th Floor has online is a great watch.
