I use a KFL+ Clone (Tobeco). Works amazingly most of the time. But every now and then, it will leak from the air intake. If I flip the tank and leave it for a while (maybe 30 minutes), I'll use it again with no issues. Maybe I'm pulling too hard or frequently? I do tend to chain vape. And it doesn't happen often. I just hate wasted juice, any wasted juice. Any ideas?
