VV: Just a quick thought, since I don't recall your mentioning how long you hold the switch up.
If you haven't already, try holding up the switch the whole time. Push the switch, count to 30 or so, and then start taking hits. Take normal full strength hits. After the first hit, which will normally NOT show any vapor, but should have some taste, keep holding the switch, pause for 10 seconds, and then take another full strength hit, which also may not have a lot of vapor. Then pause for 10 seconds, and take another hit. Repeat as necessary. By the third or fourth hit, you should be getting vapor, and the T1 should start to get hot. By the fifth or sixth hit, the T1 should absolutely be hot to hold. (Not too hot to hold, but hot while you're holding it).
Keeping the battery switch up continuously will appreciably reduce your battery time, but it will tell you if your T1 is working OK, and if that's the case, then refining your technique to get more hits per battery load can come second. I also recall that early on in the thread you mentioned that your draw was severely restricted as compared to other vapes you have used. My T1 is only very slightly restricted; maybe it's primarily an airflow problem, which will definitely cause a T1 to work poorly. If restricted air flow is the root of the problem, maybe we can go back and examine what might be causing it.
I understand that you may be frustrated beyond wanting to experiment further. Most of us here don't think you're being difficult, just upset that you can't seem to get your T1 working, and we'd like to help if we can.
