as far as vaporizers go, I LOVE my HerbalAire :thumbsup: ... I can see no reason to spend more $$$ to buy a Volcano ... they seem to be very well-made, and durable ... as to wanting to fill your bags faster, you could always buy a slightly larger aquarium airpump (but don't overdo it, as you may move too much air for the heating element to keep up with) ... :jointsmile:
