Hello! New member here! I've been stalking the forums for awhile now and learning a lot! Starting vaping, oh about December 2014. I went from 2 packs of analog cigs per day to about 6/day. (tougher to quit all together when the live in smokes at night lol) Thrilled with it and really enjoying trying different ejuice and investigating and learning. I currently have an MVP 2.0 mod, and using a Nautilus (Aspire - mini). Now keep in mine I'm a massive chain vaper when I ask this...but I notice issues with both my Aspire clearomizers. I can't tell if it's the MVP threading that is off - or if it's one of my tanks, because I'm having difficultly screwing my tank on. Started with one of my tanks, and I thought maybe the pin wasn't depressing enough to be able to screw it on properly. I thought "gee, glad I have a 2nd one..but now my 2nd tank is being 'iffy' as well. Am I just using the hell out of my mod too much? Possibly stripping it by changing tanks often? Does anyone even know if it's possible to buy just the bottom attachment to the aspire nautiluses and/or has anyone had this issue with the MVP 2? (Would love to buy another mod - but not sure which one...meanwhile dealing with this is making me panic. I hope it's not the mod! I don't want to return to smoking but low on funds. Appreciate any input!
