Review on iStorage datAshur 16GB Secure Flash Drive - Password Protected, Dust and Water Resistant, Portable, Military Grade Hardware Encryption USB 2.0 IS-FL-DA-256-16 by Michael Miles

This USB device works exactly as expected - establish a passcode and all your content is encrypted. It's all completely self-contained so you don't need to install any software, and it works with any device that reads a regular USB drive. Press the button again or pull out the joystick and it will lock automatically. Try the wrong code too many times and everything will be erased. All my project teams now carry them with them as they give clients confidence that their data will not be lost on the train or left unprotected.
