My Vapor Genie Aluminum is an extremely heavy hitter for those whole have learned the Genie Way. Combustion lurks but I keep it away most of the time. Not using it as much with Arizers filling most needs.
Using it at the moment with Mothers Hashplant (Bodhi).
My Asthma is triggered by certain dry herb vaporizers even more than smoking. A bit unpredictable. What really works for me are any Arizer portable with inverted dome screen. I also have done well with Healthy Rips Furry Edge and Vapor Genie.
Log Vapes work also and I have one plugged in all...
Nothing easier to keep clean than any of the Arizers, broken up buds are fine so grinding is optional. Going out on the back deck right now with an Air SE and some very nice herb, Redbuds are in full bloom down the hill.
