i'm good. i'm still vaping the 380mah KR battery until it dies and the 901 is just fine. i still have a pristine 901 and my son is using my other iken LR 901 that i can steal back if i have to
i still haven't tried my fusion cartos yet, so i have them as back up too lol. i think i like breaking in one good and using it until it dies before cracking a new one
