Out of nowhere my Shorty died, it lights up, but produces no vapor. i troubleshooted and called a friend of mine and put my cartos on his and they work great. but not on mine. i've cleaned the battery, checked the air holes, checked the center pin(saw a post from leaford back in nov. about the spring being too soft) all that has checked out...i don't know what else to do and i'm trying my hardest to not go buy a pack of smokes....i got the battery last tues. and for 2 days i've been doing nothing but googling and reading threads on here...can anyone please help, i'm running out of ideas and on a very very tight budget at the moment.8-o
