I know this thread is really supposed to be about Itty Bitty Mods...but wanted to comment real quick: My juice is very clear and I use mostly PG, so maybe that is why the cartos lasted well for me. I only vape one flavor, and always have (I used carto tanks for nearly 4 years, interspersed with my experiments with other gear). The flavor did mute a little after a week or so, but would still taste good and the vapor continued to be satisfying. Perhaps that was because I DIY a very strong tasting menthol.Maybe your taste buds woke up and you started noticing the bad taste? In my experience, a cartomizer is only capable of vaporizing 6-10 ml of ejuice before the flavor and vapor production begin to diminish. Perhaps a bit more if you vape clean, clear juices, maybe a bit less if your juices are dark and sweet or NETs. Tanked cartos last longer because they are constantly kept fully saturated. But you can't expect miracles--cartomizers are by their very nature very disposable.
How many milliliters was that? I have never been able to enjoy a cartomizer for 3 weeks (2-3 ml a day or so?)--no matter what kind of juice I used.
Your GS Air tanks come with dual-coil atties, so right there your juice consumption almost doubles (depending on your wattage, also). A GS Air tank is like vaping two single coil cartomizers at once.
Don't know why some cartos lasted 3 weeks. But they did. I used 45mm cartos. Averaged around 6 to 8 ml. a day. My husband still uses the carto tanks with a more colored juice (double mint) also high PG, and he sometimes gets 3 weeks. Most usually around 10 days to 2 weeks, though. He is a medium vaper though. Not as heavy vaping as I am.
The dual coil thing makes sense, and thank you for reminding me! Makes me feel a bit better that I'm not going completely nuts going through so much juice!
) is fine, although I still prefer curves. I've gotten used to the hand feel (
