Volcano is the best and of course most expensive. I saw a vapo brothers one....didnt look like something I wanted to try...espically high. Finally got to try a volcano.....hands down the best. Save your money and get that one. I put my order in for one today...should be here tomorrow. Also the high is a bit different....still good. I thought some flavor was lost but thats just me. All I know is that my lungs felt better today than they have in years...and no morning coughing....so its worth 539.00 bucks to breath like this every day
