Frank,
I recently made a trip to the Phoenix, Scottsdale Arizona area where red light cameras, fixed speed cameras, and speed-on-green cameras rule the day and I must say the Cheetah GPSMirror performed flawlessly. The maturity of the GPSMirror is self-evident, as one would expect from a company that has been combating the scourge of photo enforcement that is rampant throughout the Europe.
We are in the process of preparing a more formal review of this fascinating and useful "Big Brother" countermeasure.
