I was wondering if individual parts will be made available for those of us who rebuild our own heads? I have noticed that after a few rebuilds that the little rubber grommet that insulates the positive connector at the very bottom of them head is starting to show too much wear. In some cases I have had to throw a couple away because they were burnt, or just starting to disintegrate after a couple of months worth of serious vaping. I found 32g Kanthal wire and 100% cotton wick that works great for rebuilding these heads, and provides absolutely awesome flavor. I can't however find these grommets anywhere. Is there anyway possible to order some of these? Or I guess I will have to break down and buy the newer version heads. I still have the original version tank, and have had no problems with it. I would hate to screw up a good thing.
