Thsi is no joke, I almost died as a direct result of this kanger mod. I have had my Provari for many years and am quite accustomed to it's functionality. I am out of town and bored out of my mind and decided to stop by a vape shop to kill some time before dinner with some colleagues. I had just bought this top box and the sales person was filling it for me when my colleagues called me to say they were waiting for me to go to dinner. So, I grab my crap, hop in the car and that's when the kanger tried to kill me. I was making a left turn out of the parking lot across traffic and massive clouds came out of my mouth. It was total whiteout condition. I am in the middle of the road going 20+mph and can't see anything. I could have killed somebody. If my story saves just 1 life, it will be worth all the embarrassment of telling it. Be safe.
