I bought three boxes. Told me something was wrong with their cc machine and if I needed the boxes quicker to wire the money. I got the boxes, they don't work. I have called and emailed him over 20 times the last 4 months. No returned call or email. I then sent a email to the editor of Forbes who wrote the article on them and told him what happened. I got no rep side also. So I am also concerned with the amount of quality of information thy now comes from Forbes articles!
