It's interesting how vaping dry material varies. I was getting crazy vapor with one type of material, then the next, I was getting somewhat decent clouds on setting 2, would stir, top it off and continue to get good vapor then bump to three after about 10 minutes, stir add a little more and keeps producing clouds for a good 20 minutes, bump up to 4 until the battery dies. I charge up and still get some good capor before I dump it.
Then I had another material and was getting hardly any vapor at all on any setting until I dried it out and then got good vapor in setting 2, then 3 and 4 then 5.
Have a different material I'm currently using and I was getting no vapor. Then I packed it down super tight and hard as hell to draw vapor but I was getting very nice clouds at the end of 2, and then good on 3, stopped getting noticeable vapor and taste and it was pretty much done.
I strongly feel like this needs a good heat up period to where the chamber is consistently being heated. I always start at 2 and stay there for a good ten minutes, just pressing the go button right after it went to standby. When I start getting less and less vapor I bump it up to 3 and stay there for a good while pressing go as soon as it turns to standby.
And sometimes I just get no vapor at all so I have to fiddle. I take out the screen clean it, clean the chamber, break material down finer, let it dry out, pack it somewhat tight or pack it super tight. Also the fill level of the chamber seems to affect performance but I haven't done controlled trials to see exactly how, I just know I fill it 3/4 like the manual says and get good results and sometimes not at all, then I fill it to the black lining with just enough room for the cap, and get good results, sometimes I get nothing.
If I mess up the heating process by forgetting it went Green for Go! Or wait too long in between standby I feel like the material gets wasted and I can't get it chugging again until I empty and start over.
I also never go above setting 5 and in my experience going too high is uncomfortable for my teeth. When I try 6 or 7 I get one or two good vapor draws and then that's it and it's all burned up!
