I received an infinity today from a member here after my mom and sister got one, and it was vaping like a champ all day till right before im about to go to bed and i hit it one last time, and then something happens...my atty is firing without the button being held down...i hurried up and unscrewed it because it was getting HOT, hit the button a couple times and it lit up then went off, screwed it back on and it is still happening...am i the only one this has happened to? and what can i do to fix it? ill check back in the morning and hopefully i have an answer...i will be devestated if i have to send this in!
