It won't turn on. Just bought it
Probably...but welcome to VU....I think I got sold a defective mod
without further information.. it sounds like the +pin on your tank was extended to far. Putting it on, screwed it in more, so it fit better. Just an educated guess. OR it could have pushed the 510 pin down a bit farther on the mod. Either way.. it works now. Happy vaping.Well now I am able to fully screw it on. Don't know what the issue was but it is working perfectly now. Thanks for all the help
