I have been using 510 atomizers for the last four months and thats all I use. Sometimes after a drag I let it sit and I smell something burning. Its my atomizer. I clinch my teeth and quickly unscrew the hot atomizer and take out the half burnt cart out. I don't understand it. I cleaned it and the connection and it continues to do it every once in a while. It just started to happen to my LR 510 atomizer today and I had it for about 2 weeks. What could I do about this problem?
