Folks, got my Q8 today and top battery tube o-ring was caught in the threads when they screwed a light head onto the tube and it ruined the o-ring it is cut now. Contacted Thorfire and they told me to go pack sand, they do not stock or sell those o-rings. Banggood asked me canned question for the picture when I already included pciture of the issue, they simply do not even review. With that what o-ring do I need to buy and from where? Much appreciate the help. The price we pay to buy “budget” from budget sources
