I don't have a STM, but this sounds pretty much like what I experienced with the evic -- it would
vape great for a while, but then for no apparent reason, after about a day-ish, I'd notice the resistance had changed (though mine were nothing near that low), and hardly get anything at all from it. I would sometimes switch it to Ni instead of Ti, and then I could get a
vape, but it would taste burnt. and yes i set the temp lower with Ni; didn't matter, it always tasted burnt with the Ni setting.
I just got tired of the inconsistency and futzing around with it, and sold it. With regular kanthal
coils, I can *depend* on my vape.
