Last night I used my DBV for the first time, and I had some questions. First, no matter what I did I couldn't get a visible vapor, even when I turned the element up (I'm guessing I was pulling too hard, but I really wasn't pulling THAT hard and I've vaped plenty of times before). Also, when my unit is turned up to full power the light glows bright, but when I cut it back to 50% or so the light almost looks like it goes out, and I was wondering how bright it should be from others who have a DBV, maybe it's only supposed to slightly glow, it just didn't seem as though it was all that hot. Anyway, the first pull gave me a little visible vapor, but after that I couldn't get any visible vapor no matter what I did. I didn't put very much bud in at all, which could've contributed to it, but no matter how high I put the DBV I couldn't get the bud to totally brown much less turn black (obviously not what I was going for anyway, but it would've been nice to know I was getting some heat). Anyone had any similar issues? Any advice would be appreciated.
