I have probably wasted enough juice to last me the rest of the year on my AVS, one day it works perfectly the next three cant get the damn thing to work at all(leaking, flooding atomizer). I've cleaned it, changed all the o-rings, and toyed with every control ring position possible, very difficult to get consistency out of this thing!! For the money spent it should work better without all the toying i have to do, i don't have time to mess with this thing everyday and it seems as soon as i leave the house it just starts leaking... I have been vaping for almost 2 yrs. and using GG products for the last yr., Im probably a thousand dollars into this device(attys etc.) and still go back to dripping... I'm frustrated with it because of money spent, I feel like the cost of this thing it should work properly all the time!!! Like i said sometimes it does work flawlessly but most of the time i feel im cleaning, tightening, loosening, changing atomizer(realize made in china), changing juice, etc. Guess i should just sell this thing (AVS&AFS)and go back to dripping.. Love your products Imeo but for money invested it's more frustrating than its worth IMO. Vape on
