Yea ok I will keep that in mind. I'm about 5.2 with the HH. Im using 4.5 with my LR atty I have left over. The provari is amazing. I was using the same atty on the ego and I felt that it was getting weaker and weaker (ive been vaping for a year+). Popped it into the provari, and damn, just like new but even harder hitting. And to imagine, I almost backed out at the last second when buying it due to price. I do have another question for you guys though. When charging the batteries, is it better to supervise it or can I just leave it on overnight while I sleep? Oh, and also, will the battery continue to slowly drain if im not vaping and the provari master off switch isn't activated?
