The ohms keep wandering on my topside. It happens most with my Dpro Mini, but happens on my Dead Rabbit RTA, and a couple of others. I've cleaned and reseated the posts and insulators. The grub screws are both tight and fully trapping the coil legs. any ideas guys? Ps. Best point out the mods is claiming I have a new atty whenever it try to vape. I do realise ohms wander with all TC wires.
