Ive been vaping for about 3 months now and im not new by any means. Ive built about 40 box mods ranging from the normal 3.7v up to 6v. A problem ive been having for the past month or so is that every atty i screw in, first seems like its fried since it wont do anything. in order to get a hit i have to unscrew the atty all the way out then hit the button and screw the atty all the way back in while holding the button, to get it to hit. Ive trouble shot with all of my box mods, my e-go passthrough, my 5v passthrough, my normal batteries, and my chuck. It happens with normal attys and low resistant attys. all are 510s so im at a total loss. every device works fine with cartomizers just not attys for some reason. . . any one have any ideas what could be wrong? the first month i didnt have this problem with any of my devices.
