I have a volcano and a vapor bros. The volcano just plain out kicks ass and is extremely convenient to use at home, but not from your car....but medicating in your car isn't the best idea. Cleaning and using while heavily medicated is super easy and safe. I think what makes it so good is the controlled air and temp which combine to equal consistency.

The vapor bros on the other hand, is much more complicated to use when you're medicated, not even half as efficient as the volcano and consistency stinks without a lot of practice. Its not that hard to operate, but of course once you've tried a volcano, everything else just seems more complicated than they need to be. If anyone's interested in a vapor bros in OC, I'm willing to sell mine or trade it for something. However, its just the main unit, no whip. Send me a message on my_space under the same name.
