if I couldn't get it through an airport in Australia, there is no way I would even try in the US.
When we sold zappers for experimental use by humans, many of our customers travelled with their zappers and had no problems.
The only time that I ever heard of any problem is when the FBI called from an airport in California inquiring if the unit (competitors product) that they had was safe. I explained what to look for, they did and found it was safe.
>- as an outsider looking in, it is frightening to me just how little freedom you actually have left.
You are absolutely right and the funny thing is how few realize this. I have personally experienced what extremes some government agencies will go to.
