I have to have the cap quite loose, otherwise it'll bind when I heat it - 2 to 3 revolutions. I'm rapidly getting sick of having to freeze it after every bowl cos due to the nature of what I'm vaping, I forget to loosen it. To be clear, I'm not cranking it down, just tightening it til I feel some feedback.It should not be normal but it is like that. Fotunately you don’t need to screw it all the way down. I suggest you to stop screwing as soon as you feel a little resistance. Also, if you use a plier to unscrew it while hot, use the same plier to screw it. This issue is present on V2 very badly and still on V3 but it’s alot better.
Funny on V1 this issue wasn’t there.
