I have what I believe is a "joyetech E-go dr.e " , And I'm trying to figure out how to use it, I got it second hand so I dont have the manual, and all manuals I can find online say to use liquid but the person I got it from claims they were using dry herbs. anyone? Also, If I can use it for dry herbs, What am I doing wrong? I've tried pressing the button 5 times several times to "heat it up" and all i get is different colors and no heat. The colors I see are Orange at first, then I pressed it 5 times and it was dark blue, another 5 times and it was almost a white.
