i only say quality because that is there claim, not mine, i havent tried it, i have my quality vaporizer and it works so good, i dont smoke anymore, except once when the neighbor was smoking a bowl, but i took small hits because it felt like heart burn in my lungs after using the clean clear vaporizer..... before i had cheap vaporizers, and i still used to smoke and vaporize, but now that i have this AroMed, i dont want to smoke at all, even if i need to haul this vaporizer around, i just consider it my futuristic bong, everybody likes it, and it is halarious when i walk into a group of people carrying the AroMed, everyone is always ready to try it, and when they try this thing, they do get the true vaporizing experience, and everyone sais wow thats heavy, no complaints ever, unlike i had complaints all the time with my other 2 vaporizers that are in the trash now...
