Unless someone can open up the box, and do something to the board, there is no usb port to update firmware, charge the device, etc. If its working great, why mess with it? that's what a DNA 200 device is for. I'm a set it and forget it vaper...Thanks, I kept seeing videos where people were saying they used some software to tweak their devices, battery % was the most common. I come from hobbies of firearms and diesel trucks where nothing remains stock for long so I was wondering if there were some simple mods that the more advanced users have done and would recommend. Maybe I am in the wrong crowd, lol!!! ?
