Not getting anything close to the clouds I've seen on video with either nug or grind. (killer meds)
Been at 6.5 and 7.5 like the directions say, but only getting wisps of lite vapor.
Something sounds wrong, have you preheated the unit at least 3-5 minutes for optimal performance?
You can start a t 10 then after a few minutes tun it down to desired temp, 7+ for larger clouds!!
If you put whole nug it intensifies the flavor a bit , but the clouds will be a bit thinner but still visible.
If you grind or grind after you have hit the dry nug once , then you can achieve way larger clouds.
I have found that in my dry stem I can only load a tiny amount before it s to full and will scorch slightly from 7-7.5, on the other hand I got my screened gong and the screen sit further down creating a larger deeper space than the dry stem. This allows me to load a bit more (approx.0.1-0.13) and I can bump it up to 8 now and get really large clouds grinded.
The wood at 7 should feel warm, @ 7.5 + it can start feeling pretty hot ,not burning hot but hot.!!!!
I hope you get it dialed in, let us know how it works out for you.
Andy has some of the best customer service, maybe shoot him an email asking if this sounds normal.
Worst case you might have a defective unit, but seeing how well built these are ,I cant see many failure rates but it is possible.
Just be patient and willing to spend the time to "figure it out" 
Those first hits are a killer in taste!
