Hey guys I have an Nzonic V4 that i recently purchased. I love this thing but one thing that is stumping me is every so often it seems to misfire. If i let it sit on my desk or where have you, it will be just fine and fire repeatedly with about a minutes rest in between pulls. If im chain vaping on it however (got new liquids to try so this is how i noticed) it will fire 2-3 times and then wont fire at all. At first i figured i was just moving the locking ring with my finger so i made sure that was turned completely off, that hasnt fixed the issue. Then I noticed the tubes would come unthreaded a slight amount and retightened those... still no fix. So i tore it down and cleaned all the contacts on the atty and the mod and im still having the issue. Im useing an MNKE 30amp and its freshly charged with my nitecore i4. I have swapped batteries and all that so im at a loss. While this issue isnt big enough for me to put down the device completely its still frustrating and i havent been able to find a fix with a normal web search, so does anyone have any ideas as to what could be the culprit of this problem?
