Anyone out there tried a skillet/coil combination that works better than the stupid stock one that comes with it? I ordered the whole kit on ebay and was only disappointed with one aspect of the pen. The coil seemed to be untangling itself as I vaped. It was a goner, (the coil,) within about 24 hours . Luckily, my buddy down the street happened to have an extra globe/skillet laying around that he sold me for a measly 5 schillings. This isn't the first time I've used a skillet with a coil, so to me this one seemed noticeably fragile. Anyone have any experience upgrading the coils on microvaped pens or similar 510 threaded pens? If so what are the + and -. any feedback is greatly appreciated.
