i was doing some really intensive googling for my ideal vape unit, and stumbled across what I consider to be the holy grail of vaporizers. http://aromed.com/en/aromed.html It sounds like a dream. it vaporizes your herbals while at the same time vaporizing water, then delivers you a combination of both. OR, can also vaporize any sort of oil while you consume your herbals. You'll get a combination of both. It's a DRAW BASED VAPORIZER- The system vapes when it FEELS YOU INHALING. Anyways, back to brass tacks. Currently, it's only being sold by a medical research company. They arent even marketing it at the general public, but you can get one if you contact the company directly. I feel like this could be the mother theresa of all vaporizers, but I don't have the money to take a gamble on it. If anyone else does, PLEASE PLEASE PLEASE just let me know if it pays off. Because I'd be their sevcond customer.
