I just got a new USB Passthrough today. I LOVE IT!!! I have noticed, however, that there are times when the light turns on by itself without me puffing on it. Maybe it is the micro switch inside the battery tube that is causing it. I'm wondering if it is sending power to the atomizer while the light is coming on. That could burn out the atomizer, right? I'm hoping that is not the case. Does anyone have any answers for me?
