Alright. Panzier blackhawk clone i think? not too sure got it from a friend. I got the standard battery sorry im new to this, 18350 i think? Anyways, when I use it the button gets super hot. I checked to see if there was a connection issue so I took a knife and alcohol and removed the residue on it but that didn't fix anything. Also, it only vapes like half the time I press the button, like I have to press it in different places for it to actually produce heat. I dont think its the battery because it works fine in my brothers mod, but sometimes after vaping with it in the panzier theres a black ring around it where it was making contact. I also dont really have t o hold it down long, like 2 seconds and u can feel the heat really building it. What you do think is the issue? Ill do minor modifications if i have to
