No offense, but that is not the same as giving a machine to a few trusted members such as Dogie for review.  Offering a coupon may seem like a good way to get a few out into the wild, but your still requiring people to send you money up front, which we all know never goes well.  Please reconsider asking someone to write up a review of a unit and I guarantee you will make more profit from being a trusted seller than the expense it would cost to give that unit away.

EDIT: I just watched the video and looked at your pictures, and again no offense, but there is nothing concrete there that shows a unit actually working.  Most people can make a case like that and have something flash on a screen with little to no effort.  I am not calling you a scam, but we have seen these things over and over again with fictitious products.
