@Falconeer @sonicbomb @Hawise @Electrodave @englishmick thanks for input
not much as such; been out most of the day using the MTL on it.
one thing i am certain of that the stainless steel is itself stripy(?)/threaded-like(?_ not sure the term. maybe it was more pronounced when hot.
heat: never reached much. just warm.
_indeed for one of the couple of times, i felt the heat more with one hand than the other and a-duckduckgoing...
_it only happens when i've been chaining for a few hours.
_only with the subohm
@stols001 suggested on another thread when i was asking about a leaking problem and the fire-button sticking, suggested she the anna it may the leak caused the group of events.
it doth leak when i fill it up, even with 70VG, just overfloods, gurgles and leaks thru hole, and that's despite UWell's so-called liquid recycling thing... she'd said something about taking it apart, but incompetent as i am... and having contacted uwell about the fire-button sticking_ don't want to void the warranty which i probably won't get: they want a video of the button sticking, which is very difficult to catch even if i had the self-restraint to let it fire on as i unlock the stupid phone and capture it...
at this point i'm suspecting any of this is actually happening though, and i honestly don't want to rip them off , so not sure to press the matter
