About an hour into my work day I wasn't getting any vapor. Checked my atty for shorts, checked my mod for oxidized contacts, adjusted the little screw for battery contact....coils were barely putting out vapor. I thought maybe my clone bworked up. I was ...... I only have this one little atty at the moment. Get home and check my battery it's almost completely dead. Fail.
