I haven't tried the mighty Volcano, but I own a Vapolution. We broke the vaporizer virginity veil together. So anyway, I love it. It is very portable too. I've tried some others since like the Vaporwarez and it works alright, but wasn't hands free. If you have unlimited funds and desire portability and a better taste, you might try something like a Vapolution...
That's my $4.20 worth.
