Review on PortaPow USB Data Blocker (Black) - Secure Against Juice Jacking Safely by Seth Damain

It cost me almost as much to ship this product as the product itself. Six dollars to ship a $7 item seems like a lot doesn't it? The envelope and stamp are not that expensive! As for the data blocker, I haven't used it yet. I only bought it in case a situation arises where I really need to use it. It looks good and I assume it works, but that's about all I can tell you about it. Only gave one star because. Well I haven't used it yet so I don't know how it works. It might be worth five stars but I really can't tell at this point.
