Why is it that....

So many of the people on here seem to change the coil heads on their stardusts and other tanks so regularly. I have only changed one head in my whole 4 months vaping. I don't really notice that the flavour has gone bad or anything and I've never burned out a coil. I only changed that one head cause the wicks were falling out. Is there something that is making my heads last longer? And what is everyone's average life for a coil?

My heads last at least a couple months. I usually build a new one because my wicks degrade first.

I have some coils that will last me a week and some that will last me a month. It really depends on what flavor I'm vaping. Some flavors I like better at 3v and some at 5v.

Also, some people, like my dad, will replace their head, coils, or what have you weekly regardless if it'd going bad or not

My first Kanger T3 head lasted me 20 weeks. It would have lasted longer but while I was trying to get the old wick fragments to install cotton wicks I inadvertently grabbed a coil and pulled the whole thing out of shape. Now I'm using that one to practice rebuilding and replacing the coil with a new one. So-so results so far. Using Kanthal A1 32 gauge with 5 wraps on a 4-40 machine screw I'm getting 3.18 ohms. Maybe I should try winding it on something smaller, however others using the machine screw seem to come out right at 2.5 ohms.

An original T3 head has 7 wraps and checks out at 2.5 ohms. I wonder what they are using?

My experience has been that different juices will gunk the coils differently. When they get really bad, the buildup reduces the vapor (although the coil is still heating below the gunk, juice can't efficiently get to it.)

I find the cost of a new coil a reasonable expense, although lots of ECFers clean / dry burn them.
