Hey Chellby,
First off welcome to the best combustion fucking forum ever.
If you haven't read thru this thread yet I recommend it highly (pun fully intended). Great info and only 20 pages so not a lot to search thru.
What I do with my screens is this:
1. Take out ceramic filter from mouthpiece and discard.
2. Load material into T-vape while screwed into battery.
3. Push screen from top (where the mouthpiece goes) onto material. I don't pack it down, just push until I feel some slight resistance from the material.
4. Turn unit over and unscrew from battery.
5. Take a second screen and push in against material so that it is at least 1/2" to 3/4" off of the bottom. (Reason for this is because there is a dead spot directly over the silicone cap on the battery that does not heat)
6. Screw battery back into oven, put mouthpiece on and enjoy.
The T-vape really "could be" a nice portable option that can milk any of my glass big time when used correctly (while reading through the thread take a look at my video milking some chinese glass with it, don't mind the In and Out burger advertisement in the background, we had gotten a little off subject talking about munchies and the Mods Modded it - thanks by the way mods, some of the threads here might look like stoners were running them if you guys didn't clean up all the time!) Speaking of correct usage, below is a post by Rude Boy that really made the T-vape come together for me.
Now the bad stuff.
1. Taste is not great.
2. Off Gassing happens on a lot of the ovens. When you receive it make sure to do a burn in (run the unit empty like you had something in it), and check for any vapors. My first oven was horrible (literally smoked) so got a second one and it is much better, but still got a little unknown vapor.
3. Customer service was almost non-existent for me. I emailed there customer service person and did not receive an email back for over a month. Told them the issue with the off-gassing and did not hear anything back so I decided to buy another oven to try out. Finally got a response another month later with a return authorization (I have not sent back the oven that had bad off gassing yet, but will be in the next week.)
I do believe that the concept of the heater is good and works very well, but to be honest I did not feel that health wise it could meet my expectations.
Hopefully you get an oven that does not off-gas because I really like the T-vape but have recently switched my daily driver to a Lotus and haven't looked back.
Here is that post on correct usage (Throw out the manual when you receive it!) Good luck and welcome back. With this forums help you will have 6 new vapes and 4-5 new glass pieces by the end of the year. Damn VAS GAS.
