If I had to recommend a single vaporizer that is the all around best, and most usable in the most situations I know exactly which one I would pick. It isn’t the prettiest, or the newest, or even the most high tech. It doesn’t flash and glow, or beep at you, or anything like that. What it does is work and work extremely well. What it is is the Volcano Vaporizer all the way from Germany, and it is by far and away the very best. You are going to pay for the very best, but settling for less is foolish, and one might as well discontinue medicating, or just smoke it. All of the cheaper vaporizer units have some kind of major drawback. The biggest one being none are medical grade. They are all billed as, “aroma therapy” devices, and are essentially that. This is an actual medical device, made for the medical industry in the forefront of the medical industry. Like any medical instrument it has to be precision built to the highest standards, and be easy to use. To achieve this the German manufacturer, Storz & Bickel hand builds and inspects each one from scratch, with only the finest medical grade, and food safe materials. Many many hours went into researching the proper materials that could be used in a device that has such fluctuating temperature extremes. All of that research and the hassle of building by hand have apparently paid off though, because these things have been the leader in home herbal vaporization, and medicinal use since its introduction to the market in 1997. There have been no design changes to the unit at large in that time frame, and that is something no competitor can even remotely come close to saying. If you can pay for the Mercedes Benz of weed vaporization, it is well worth it, and not even worth the time to look at others.
