I have a Vapolution and it's the best thing I've ever purchased! I prefer it over all others that I've tried (Volcano included) for many reasons. How many of the above units can you throw (literally) in your car, use safely without any dangerous hot exposed parts (VaporBros) and vape the shit out of a little bud and get ripped, then drop the tank on the concrete when getting out of the car and it works like a charmed vaporizer still?!!! This unit deserves the reputation it's building. Also no parts that will break down or wear out over time (like the blower in the Volcano). All you have to do is use the lungs you were given to suck it out...who needs a little motor blowing vapors in a bag for them? Certain medical users certainly, but I would put the Vapolution up against the Volcano anyday, and watch it come out the winner. Seen that happen with three people now.

Peace and Happy Vaping!!!
