I wish it was mine but nope. I'll probly change it a couple of times in the next few daze.
If you buy pre fills and top them off with the same juice there's no need to clean them everytime until they start tasting funky. I go through about 3-4 ml a day so I'd go broke quick tossing them. Average carto life, refilling, seems to be between a week and two if you use SI's juice. I've heard of a month but I've never got that long. Using heavier vg and dark thick flavors diminishes that quite a bit for me. YMMV. I still do it but know I'm writing off longevity. Gotta pay for my pleasure.
I regularly get 2, 3 months off the same carto w/the same juice...even the DARKEST and most carto killing juices! NO cleaning in between fills, just a few drops every 5 or 6 hours. I have a carto that has had the same juice, same carto, no cleaning since Aug 2011. and I use it EVERYDAY.
I would be very upset if each carto did not last at LEAST 1 to 3 months! and they do that for me. Not sure what the rest of you are doing with them LOL!
K fine, I have at least 10 to 30 going each day, so guess I'm not as hard on them as some of you....
