I rotate between my SmokTech Z-Max V2 and sigelei Z-Max OLED with no issues whatsoever! As a matter of fact, I actually prefer them over my two Provari's. As an aside...clearo heads can be rather inconsistent, and in my experience, for every ten...two will be dodgy. This is with Splitfires as well as Kanger T2/T3. I would also recommend against the rather daft urge to dry burn silica wicks...never understood why people do that.
