Think I mentioned this before, been using a super vapezilla for close to 2 years now & she's been more than adequate. Purchased an extra one for 100$ just in case. Don't know comparisons but hear the Volcano is tops? Also know that the one made with Pyrex type glass are the best. Ya want glass/metals that do not emit toxic vapors when hot. That's the key if ya didn't know. Peace
