thankfully i haven't had that issue but I could see it happening, especially with rda's some of mine are very close (if not touching) the top of the coil but hasn't been an issue as of yet. would just need to I guess be aware it you have a short rda.
i don't do metal drip tips either for that reason, too many burnt lips.
