I'm no good with e cigs/vapes I usually get my friend to just tell me what's good to buy and what's wrong but he doesn't know what's wrong this time either.. Basically I have a COV mini volt with a Kangertech aero tank 2 and for some reason for the past two nights in a row it keeps saying no atomiser after I fill up but I'm not doing anything different so I tried loosening it, tightening it and cleaning the connections and turnings it on and off but I just won't work again apart from yesterday when it just randomly started to work again after my other friend unscrewed it and turned it off and on again but that's what I'd been doing all night and day.. Does anyone know what might be wrong is it fixable or do I just need a new one?? Thanks.
