It's a bad ohm reader, don't trust it.
I've heard pretty good things about the Smoktech Ohm Reader, but I haven't tried it myself. I use my MVP and my IPV3 to read the ohms of my
coils (all the ohm readers I've had don't compare to the MVP2). I don't usually go super-sub-ohm though, I try to stay in the .3-1 ohm range.
Also I'm notorious for going a LONG time before rebuilding my
coils. When I make a build I like, I stick to it for a long, long time (oldest coil I have is probably 9 months, after a quick rinse and rub it looks brand new). It guarantees reliability for me (I know what ohm to expect all the time), I could care less about a "clapton coil" or "Hendrix coil" or whatever. If I can achieve "it tastes nice" with some simple micro/macro
coils, that's all I need. [/rant]
Although, I do wanna try out some of that twisted kanthal.
