Ive used the phantom pura. Whats funny is my buddy just sold his. Wish i would of known earlier. She could of sent it your way.
There was two negative things i found about the phantom
1) Takes a while to fill up ballon
2) Ballon can melt against heating element
Well i think the only thing that makes the volcano better is that it fills balloons super quick compared to phantom. I believe there balloons can melt as well if your not careful
For the price i would go with the phantom for sure. I know there is the AirQ vaporizer around but i have never used it. Just letting you know wasnt sure if you checked it out or not. I do believe its more expensive than the phantom. Of course cheaper than the volcano. Good luck with your search. Let me know if you have any question on the phantom. Peace out bro
