Ok so I just got the kangertech topbox mini starter kit last week it came with the 4 coils (clapton,nickel,rba,and ss) BF accidentally fried the Clapton and rba, so I used the ss one yes with the red ring and well the housing wasn't even aligned right it was faulty and caused major leakage and ended in horrible flavoring.i ordered some square .5 ohm occ vertical coils and I have tried 3 already and each one just omits a burning plastic flavor no matter what i do, I have primed It really good even let it sit well over 15 minutes,I tried the needle poking holes in the cotton trick On one,I've changed flavor and wattage from between 8 all the way to 35 even, I have tried 65vg and max vg, no matter what there is this horrible burning flavor that is making me sick.also the topbox kit has one coil left and I'm confused because the housing says it's nickel (ni .15ohm 15w-50w) yet it has a red ring not blue. Please i am so stressed and at my wits end with this mod any help is appreciated!
