I posted just posted this in another thread..

I just got one, invited a couple of friend over the same day and we all helped setting it up and researching the minutia of it's operation. I was surprised by the size of the herb receptacle. One of my buds shredded some dry, almost brown regs with the awesome grinder that comes with the Volcano, and we put a layer inside about 2mm thick. Got 3 bags of haze off that load easy, and we were all feeling it but it wasn't like an immediate stoned feeling. Like idiots, we assumed we were doing something wrong and 'lathered, rinsed, and repeated.'

Well let me tell you cowboy....

I've smoked myself silly on a few occasions (like as in, way to much) and dread the nausea that comes along with it. Doing too much with a vape is entirely different! I was stoned stupid, but there was no sense of nausea, quite an odd experience. The munchies hit hard not soon after, and we were all giggling like idiots for awhile. The even stranger part was about an hour afterwards I had an almost scary second buzz kick in. It came on so fast I just sat there, eyes wide open in disbelief and the room started to spin. I had to excuse myself and go lay down for awhile, it was almost trippy I tell you.

But no nausea at all, and I slept like a baby that night. Anyway, I view that Volcano with a whole hell of a lot of respect now...
So no coughing or gagging on big hits like with a bong or something, but also no sudden rush of being high - which is likely due to the pathetic quality of herb we used. I didn't notice any "scorching" effect that others have mentioned in relation to using a vape either, I can only guess that's common when using a whip and drawing directly from the vape. Methinks the use of a large ballon disperses the heat discharged alongside the vapor.
Anyway, spoke with a friend last night and told her of my new acquisition. She's quite intrigued, and said she's now contemplating a special trip to Vermont to retrieve something dank enough to be worthy of the metal clad German beast. I think I'll reserve ultimate judgment until I get some real weed for it.
