I got you I guess, the whole ordeal seems kinda too much for me too, especially when you can buy the coils and spare the time and patience of minding about all the nuances you need to take into consideration when rebuilding. I make my own e-juice though, else it would be more expensive than smoking cigs for me.
Get a tank with top fill the next time then, it’s really handy!
A lot of the people where I live smoke. It’s made some of them very sick. There were times when there were four or five people on oxygen machines. Also, the people who don’t smoke have a lot more discretionary money to spend.
