Hello gentlemen!
I have a Tempest about 2 weeks now. I extensively tried
@kokolokokolokon beta unit last year too.
Seeing the inconveniences some of you have i wanted to share my grain of salt and my experience with this unit so far:
As I had already tried an used Tempest before, the first things that i noticed when i received mine brand new was that the flavour was way off and clics took ages to cool down enough to click again. The bowl screw was too tight and it would have cost me a lot of effort to unscrew if i hadn´t bought a reload too.
Luckily, after about half a dozen heat cycles the flavour came back and after some more the second click started working perfectly.
It took about one week of daily usage for the bowl to become looser and it is now almost perfect. Anvil´s threading is so much better but i like that the Tempest unscrews in a single hand movement.
Right now the first clic works well once the unit is cold but it still takes north of 5 minutes to make the cooldown click so i dont use it when doing bowls back to back.
The visual indicator works wonderfully with flame, when reheating it is absolutely reliable but it is not the case if using the wand.
In my point of view there is no reason to ever open the cap and fiddle with the spring or discs unless mechanical failure which is extremely unlikely to happen in the long term if the unit is properly heated. No need to disassemble for cleaning because it can be cleaned as a whole so my suggestion is not to touch there and be patient the Tempest needs a break-in period and after it will work as intended
