Well, in wattage mode it works great out of the box. Notice that the resistance reading isn't good too, I usually get 10~20% higher resistance on gen's reading on v1.0 and 10~15% on v1.3. I think that newer gen's will be shipped with 1.0 firmware, so keep that in mind.I don’t usually use TC, I have several mods that do a swell job at TC and while I enjoy it just fine, I don’t really need it because I take pretty short pulls and don’t get burnt hits. That being the case I don’t mind that tc doesn’t work well with this mod because I’d just go back to wattage even if it did work. More of a curiosity to me than a necessary vape mode. Thanks for the heads up though
