I use the volcano daily, and it's pretty bulletproof. I've stepped on it, some tool hit the side of it and dented it...

It rocks. I don't cough all the time anymore. I don't stink of smoke.

Best part is that it's a different feeling for me, I don't need the heady high I need the body high for disc pain relief, and vaporizing seems to give me that whereas smoking seems to make me really high but not provide the pain relief I am looking for.

I pretty much demolish the plant product in there so I haven't found much use for the duff (food doesn't work for me, I've tried cooking with it) but with the volcano (and any other vaporizer) you can just keep reusing the duff too if you get to that point.

In fact, relating to that last point, I'm interested in one of the other bag style vaporizers that have a control for the fan speed, as if you could slow down the airflow initially through the duff, it would heat up more and release more active ingredients rather than half the bag being just warm air...

I will say that my volcano did break, the thermostat freaked out and would only make vapor at the #9 setting (and why really doesn't this thing go to 11) and I sent it to the repair facility in CA and they fixed it the day it got there and had it back out the door that afternoon. I was impressed.

Being able to get your machine fixed when it's broken is worth the extra money in initial cost in my book.
