Hey guys, I got a new buck naked express about a week ago from a gas station (I had to return the first one because they sold me a broken one), and it's been working great. The problem I recently starting having, is that sometimes when I try to take a drag from it, sometimes it works for about a second, and then stops vaping and blinks twice. This happens even when it's fully charged. Is this intentional? If so what why does it happen? Is it overheating maybe?
