I have a bit of a problem. I recently switched from the top coil vision/stardust type to the dual bottom coils from aspire. I have 1 anyvape davide with the aspire bdc coils and two aspire tanks with the bdc coils. For some reason when I use the VK mango madness and Flavorz by joe grape fez e-liquids the coils pop and crackle like there burning up. I get maybe a tank or so out of them and then I get really bad burnt and bland taste. is it the e-liquid im using or what.
