The privacy software is user friendly, I trust in Kingston for strength that I have neither the knowledge nor the desire to test. The finish of the key seems correct. A cord could have been delivered with the key. The flat lies rather in a certain slowness: Firstly, we are USB 2.0, then I suspect encryption to induce slow. Perfect for those like me who prefer security to the speed: I placed the key on Windows 4-door papers 1GB to 2GB each.
