That’s awesome! 👍
Going by other comments here, apparently candle wax vapor/deposits isn’t nearly as electrically conductive as nicotine/tar/ash buildup, so basically everyone saying they use theirs to light candles has indeed reported these sort of lighters for many years with no problems.
Things get a lot dirtier a lot quicker and end up eventually shorting out when used to light a pack of cigarettes a day. Yeah, bad habit I know, but at least I know how to clean and maintain mine when it starts acting up.
