Hello All, I recently purchased a few of the Kanger Protank3 mini and Kanger T3'D tanks and they are great but the coils go out in them so quickly. Previously I was re-filling the cartridges from old pre-fills from the dispensary and those worked for months until the coil began to go on them and they started spitting out concentrate. I suppose the biggest issue with the Kanger tanks is that when the coils go, they leak...a lot, from both sides. So the battery gets flooded with concentrate and you get tons of concentrate spitting into your mouth, which makes for some interesting evenings... For the e-cig folks who buy their "juice" in 30ml bottles losing a few ml's to leaking isn't the biggest loss, but when it's a cannabis concentrate that costs like $120 a ml, losing a quarter of a 1.5ml tank is a big deal.... Then on top of that the replacement coils are like $2 each, so finding out that a stupid $2 coil just cost me $50 in lost concentrate only makes it that much harder to deal with. What cartridges do you all use? Clearomisers, drip coils, sub-ohm cartridges... This is a new-ish world to me so I am still not sure how much of what is used in the e-cig world can be used for cannabis and so far what I have seen as the cartridges built for cannabis are expensive and mostly not rebuild-able (unless you count replaceable wicks as rebuild-able). Is there a trick to making the Kanger coils last longer? How long do your wicks last? Do you tanks leak? Do you rebuild your coils? I have seen lots of videos on how to rebuild the coils but I am a bit standoff-ish about this. The batteries are lithium-ion and if wires get crossed the battery will explode and catch fire. I would love to hear everyone else's thoughts. Thank you!
