I think you did kinda answer your own question.....I tend to replace my coils every few days.... I hear of people using the same coil for weeks and weeks, even a month or more......
I love that just wicked and coiled taste.....I am sort of OCD when it comes to cleaning a coil..... I burn it off, then I use little micro brushes to really clean, rinse and repeat. I even got some ss micro brushes for really getting in and around the insides of the coil and of course after all that messing with, I retest my resistance to make sure I didnt get it out of shape......
I just want a small dripper atty, with a small chamber, good taste and airflow like the Spheroid ( yes I said good airflow ) and the Phenom and well made..... I wish GP would make a drip short version of the Spheroid
So just to re cap, cause Im kinda slwooo..... THe Achilles is a dripper or a filler tank, is it smaller and does it have less air? I think if it is so, I might put that as a possible trade item in my ad.
I change my Wicks with every tank fill. 6-7ml* is the most I'd leave a wick to perform to its finest best. Whereafter it starts losing its wicking properties and I need to dry burn the coil as well. B'coz a gunked coil (even if it is slight) messes up the taste, don't they?
As re. the Coil, I can leave it in my tanks for many rewicks. I've kept the same coil for 2-3 months sometimes. But I usually get to replace them earlier just to try something new, but I know it could've lasted months.
*My Erlkonigin-Nano wicks see two tanks before replacement, it's 3ml you see.
