I can't add any more than the rest of you on the usefullness of the Box. I picked mine up on a trip to the US recently. As I was returning home, I had contact with a lonely TSA agent, a retired deputy sheriff, at the airport. I approached him and started a discussion. I asked "I notice all the signs in the airport say 'No Smoking.' What about vaporizing?" He had no clue as to what I was talking about.
I explained the process of vaporazation over combustiive smoking, different temps, different chemical reactions to vaporizing and the fact that it produced no visible smoke nor odor. I then took my brand new MF out of my bag and handed it to him to look at. Remember, it was brand new, never been used.
He took it. Looked it over and was amazed. He said that the airports would have a problem when the public found out about these things. I told him, "they already know!" And had to chuckle. He asked me if I smoked tobacco. I said yes, as if there wasn't anything else to smoke. He asked me to put a pinch of tobacco in it, go over about 10 feet from him, sit down and use it while he watched (INSIDE the terminal). No problem, just following orders, officer. I vaped a ciggie in front of him and when I finished, he agreed that there was no visible smoke and no lingering smoke odor. We both had a chuckle at that point.
I gave him enough of an education to continue. He said he'd bring it up at their next staff meeting. So, I have TSA verification that it can be used INSIDE an airport W/O notice. That's not "permission" but it's a start!
