I think you all jinxed me. I have 4 axioms, use them in pairs (when cleaning two of them the other two get used). I got them because of the price and replacement coils are inexpensive. Also plan on learning to build coils this summer, so they are a win-win-win for me. I really like them, get good flavor and enough clouds to satisfy me. I run 14w with a drip tip for more tootie-style at work, 24w with no tip for more clouds when I want.
Went through the original coils and over 20 replacements without a leak. Until yesterday. I read this thread just the day before, hence you all jinxing me

. I did flip the tank over, unscrewed the base, unscrewed the coil, wiped the base out good and re-screwed the coil back in, no problems since. I do have the air vent issue on one of them, the other three I can adjust easily on the mod. I really like them, use them probably 90% of the time, use my Cleito 120 the other 10% for when I really want to play with clouds.
