the cano has a larger area for better heat distribution
It also only does bags. Easy to have the best bag vape when it's $500+ and doesn't do direct draw.

I have the herbalAire and although it's slow, it puts the same quality of vapor in the bag as the Volcano.

After looking into them.. so far the herbalaire is looking the best. thoughts?
IMO the herbalAire is a safer buy in a dual mode vape vs. the Extreme, which has breakable glass and digital, but the Extreme, using the elbow packing method, gives better whip hits. And if you do need an out of warranty repair down the road, I think Arizer will be reasonable, cost wise.

I'd stay away from the Vapormatic. The temp varies too much and it only carries a 90 day warranty. That's awful for a $300 vape.
