Basically, my V8-T8(6.6T) coil got burnt so I switched it out with another one in the box, the V8-Q4(5.0T). After about a week it just stopped working then my mod, Sigeli 230 watt, kept saying check atomizer. I thought it was a problem with the 510 connector, however, the other coils from the package work it's just the V8-Q4(5.0T) that doesn't work. I have opened my tank thoroughly and have checked out the coil its self. Nothing is wrong with it. I have tried to contact SMOK but they still haven't responded. Can anyone please help me understand this problem?
