Sorry I was in Chicago for the weekend and didn't have my computer with me. Anyways my friend and I used the Vapir One 5.0 and I would give it a 6.5 out of 10. There are little discs that you fill with pot and those discs pop into the vaporizer. You turn on the fan, which kind of sounds like a hair dryer and that will start blowing the hot air through the disc and soon you will get vapor. The bags that come with the vaporizer are kind of small, maybe only like 2 or 3 hits. Eventually the pot will be done and you won't get anymore vapor, but after taking it out of the disc you probably could get another hit or 2, but for some reason you don't get it. I don't know if I personally would get one. I use the box style vaporizer and that works just fine. Is there something specific you were wondering? I was really high at the time and might have left something out lol.
