I was recently given an eleaf istick 50 watt mod box by a friend who got a special edition one! The only thing is that it has been sticking when I am vaping and it has started to autofire when I am not even using it? I know that I read somewhere else on here that this can be fixed fairly easy and was wondering if anyone can help in with this please??? If its not something that can be explained or something please let me know?!? Thanks for any help you can give me!!!
