I've read a few people having the same problem in the RX200 thread (with resistance jumping) and with the pin not coming up enough or recessing enough (also same problem I have), so it may be an isolated problem to certain mods from certain batches (at least that's what I'm hoping). I've had multiple TC builds that just plain wont work. Resistance won't lock, ohms raise and lower at will by unscrewing. My biggest gripe about that is that I hit Temp Protection almost immediately every time. I had a fused Ti Clapton that never would vape. In Ti mode, 40w and 600* and still hitting temp protect right away. So I tried my smok TCT with stock ni200 coils, always read around 0.15 on my ipv4, the resistance never stayed set and was also hitting temp protect at the same settings in ni200 mode.Hmmm, I haven't had that happen on either of my rx200s..
