This thing just leaks like crazy... I don't have any wick that I could add to it, as I have seen might help. And if I have to make another online purchase, honestly I think I would rather just buy another tank and scrap this thing. I really DO want it to work!! The first 2 days I had it, I thought the vape was great and I kind of liked the "airy" draw that some complain about. I had minimal leakage then, but the metallic taste was killing me!!! I did a vinegar soak and then a boil and the metallic taste is now gone, but I can't stop the leaking!!! Tried 3 different heads so far (all Kanger) and I tried filling to various different levels, all with the same results. Looks like my final option to try to save this thing might be to cannibalize a clearo for the wick. I would almost rather save the $4.00 clearo and junk the $20 tank...... At least the clearo works right now....
