I'm not sure how to explain that but I'll try... My atomizer (kayfun) made some deep scratches on that round golden thing in the front cap (is it called a circuit? A contact?). Is there anyway to change the front cap? I'm afraid my Provary may stop working due that and I wont be able to use Provape warranty since I live in Europe... I'm going to buy 510 to 510 adapter but still...
