I've followed the instructions to the letter, but weirdly enough, my sub ohm coils still give me the burnt cotton taste. I mean it doesnt taste burnt, but it certainly tastes more like cotton than it does my e-juice. It's saturated, and its been doing alright for a few hours, but it seems that every few hours i have to open it up and just tighten the coil to get it to burn e-juice again. Its weird because it's structure makes sure its always in contact, so im not really sure what exactly im fixing by rescrewing the coil in...any suggestions? The taste is disgusting, and i dont want to waste yet another coil.(the other one was my fault though, how could i have known the e-juice would run out so quickly? blame physics.)
