Hi, thanks for the suggestion, I should have mentioned I have tried that along with pretty much every step mentioned on this thread before I started commenting, luckily I’m also in the uk so I can ship it back to them next day and hopefully get the issue resolved quickly 🤞🏻I REALLY like how small and light the mod is for a 21700 and would like to use it at least once haha. I shall report back once I either have a replacement (my preferred resolution) or they have sorted it out. Thanks for all the help guys
