Kind of Vape/M
Nothing will burn out the atty as such, most all are cleanable and all parts generally are replaceable, but too high a voltage with a LR coil can easy pop them,, ie: rebuilds ( a next step in vaping ) as self fix reaps benefits two ways... satisfaction and cheaper
Coils can be rewired with ease therefore reducing cost of replacing the whole units, but a little maintenance can prolong the lifespan eg: dry burning or cleaning with alcohol of the wire...(check out some youtube vids)
Wicks can be replaced easily simply by changing with silica or SS mesh whilst the rewire takes place....wicks DO wear out or thin and or draw less fluid or if a burnt taste is evident due to dry burning the wick. it maybe time to change it.
A lot is trial and error what works for one may not work for another,,,, choice of atty, drip tip, taste, set-up etc.
