Hello all, I currently own a couple Kanger protank3's. They are good but they leak when the coil goes out and the coils seem to go out quite often. I only use the vape a few times a day and I am changing the coils every 10-14 days, it seems a bit excessive... People keep suggesting I try the Aspire Nautilus X mini. Besides having to spend the cash on the tanks, the coils cost 1/3rd more. I don't want spend the money on the tanks, only to learn later I am chained to $6 a month per tank in coil costs... I have seen videos where people rebuild the Kanger coils, and while this seems do-able if I am going to go down this route I want more "wiggle" room... So, in your opinion(s) who's coils last longer and roughly by how long? Thank you in advance for your help!!!
