The resistance seems to be changing though. anyone else have this happen?
Yes. I *think* this indicates some type of short, perhaps an intermittent one. My first coil settled out, but then I traveled with it, and it started wigging out again... I assume the coil/wick rubbed around as it jostled around in my suitcase.
When I rewrapped the coil using the cigarette paper method, this solved the issue. I've been vaping mine all day today and ohms are have been completely steady at 2.2 from the get-go (and I've been checking it frequently).
