Last week I bought the Aspire Mini Pegasus kit and was delighted. I'm using the Ni200 coil TC mode. At first it was perfection, but in the last 3 days I've been getting horrible dry hits with a metallic taste. The coil was primed properly. I have it in vape position, but it seems that it isn't wicking properly. Someone on another forum suggested it could be a vacuum problem and said to unscrew the top slightly to ease the vacuum and it would wick, which did indeed work and had seemed to fix it. However, I'm having to do it more and more and have noticed the device getting very warm as well. Is this the coil at the end of it's life? I'm having to loosen the top every other vape now to get it to wick. Any advice?
