I recently purchased an Herborizer XL 14.5mm, and when I try to plug it in to heat it up, the connection between the heating element and the dial short circuits, melting the plastic. If I angle the connection between the injector and the dial in a certain way I can get the heating element to actually heat up, but it's a pain to do. I had both of the parts replaced, but I am having the same problem. Is this a common issue with Herborizers? Modnote: Duplicate thread deleted.
