Hi my name is brendan, i just recently got back into vaping to quit my pack a day habit and its been going well. My friend gave me a istick 80w box and i bought an aspire celito 120 in hopes to move up into a better box which i now have a voopoo drag mini. The tank has been working fine on both boxes for about 2 weeks until today. Now it works perfectly on the voopoo but when i put it on the istick it reads atomizer short. I tried the same box with my aspire mini tank that i have for my 20w box on the 80w box and it works fine. Im confused as to why my celito 120 wont work anymore on both. Any help would be greatly appreciated!
