I just bought this atty about 2-3 weeks ago. I haven't used it with any devices over 3.7 and mostly with my 3.1 joye 510. Last night I was vaping and all of the sudden POOF! I felt a gush of hot air and smoke go in my mouth. I wasn't aware that these exploded like this. It never got too hot but I was using it with the wick and bridge removed. Anyone know why this happened?
