My most recent experience with Smoktechs was really bad. Out of 10, 2 were just dead dead, 4 would vary when checking resistance between 1.3 and 3.2 (did this on both the Provari V2 and a multimeter), and all had the burnt to a crisp taste in no time, which would not go away regardless of fluid level/flush with fluid. Even more amusing is that some of these had one hole punched, some had two, and some did not have a punch at all. Really awful experience with this...I'm done with Smoktech as a company for good!
