Quick question..I received my DSE901 kit in the post a few days ago. I think I have something going on with the atomizer. When I look in at it, there was what appeared to be a bit of the filler stuck to the bridge. Out with the tiny tweezers, but it doesn't look at all like the filler, more like strands of some sort of fiber, and the ends of a few of those looks scorched. Anyone know what this is? I haven't tried to use it since, I just switched to the spare I ordered. I am still using the prefilled cartridges that came with it.
