I was also in the same situation, deciding between HerbalAire and volcano. I really couldn't find any good reviews on the HA that didn't seem slightly biased, so I ate the additional cost and bought a volcano. I love it. I regret the price, but the amount I smoke will make up for it.

And about the HA extracting more from the herb, I'm not hugely worried about it. I don't vape all the way every time. Once the taste starts getting bad, I put it to the side. I'm going to use the duff (vape remains) to cook with or something, so in the end, I still win.
nicktheawesome Reviewed by nicktheawesome on . HerbalAire... Hey Guys, I am currently a vocalist at a music school and I really would like to continue my use of weed as an evening activity but I don't think I can keep it up much longer for my lungs. From what I have done for research I am gathering that HerbalAire is a great buy for those that don't wish to buy the high priced Volcano. I watched a video on it and the guy compared the HerbalAire to the Volcano. I guess the HerbalAire has a few air jets that pulsate unlike the Volcano that just has Rating: 5
