    This item is almost perfect. I've had it for more than a year, and love the secure drive capability, but the plastic key ring loop is sub par. I had it on my keys, and it broke, so I am now unable to carry this around conveniently. This is a problem inherent to the device, as the same thing happened to my wife, and coworker; both of whom also purchased this device. But for this flaw, this would have been a 5-Star purchase, but since I'm now unable to use it as intended, it's been relegated to 3-Stars.
