The VI will not take into consideration the heat soak from the first heat up and so you’ll need to heat to a lower mark.
It says in the manual to stop heating one mark earlier so it is explained.
The 2 I have, both with updated parts, on reheats there are slight differences in when I remove them from the heat, one is just as the indicator has touched the third mark, the other is when the indicator is exactly on the middle of the second mark.
No issues here, guaranteed satisfying rips every time.
If I've passed mine around there hasn't been any issues like that, I do advise folk not to inhale too strongly though, it needs time to build, if it's just been reheated and someone starts pulling on it like a monster then it will probably end in combustion.
Let them know to take longer, slower draws and that should hopefully help them out.
In my experience, it's actually pretty easy to use so I'd disagree with it being for enthusiasts only.
It's a mechanical device, so it takes a bit of dialling in, but that's common with most vapes.
Are any of you guys that recived your release unit using a torch?
I've used single and double torches, they're really good, I just prefer the convenience of the wand.
With both single and doubles, I had the flames set so they were about 1.5 inches long, I'd hold it so the outer flame was just touching the induction layer and was aiming at the top line and rotate slow and smoothly (be careful not to heat the coil directly).
To start with I removed the torch when the indicator hit the second mark, then after seeing how that roast was, I held it for a second or so after, I was getting good results, maybe slightly better than the wand, but the wand is too convenient for me to pass up.
Also, note that the VI will continue to move up after you've removed the heat, that's why you want to remove it early.
