Great detector...We actually purchased two. After using this detector on family trips (borrowed from my inlaws) we had to have one in each car.Picks up on the highway with plenty of warning...Actually found myself wondering if it was a false alarm at times as there was not a hwy patrol car in sight. 20 - 30 seconds later there he was.Easy to use instructions for more elabroate programming if desired. Although the factory settings are just fine. Auto-mute and last use memory are nice (for mode, volume and display). Good range in alert volume controls, from crazy-annoying loud to barely audiable.Very good range of brightness as well. From Very Bright (almost too bright) to Very Dim...You decide whats best for you...Does pickup the occassional false alarm in the city, banks etc seem to set it off, but on the daily routine this becomes the norm...We paid a bit more for the blue display, just because we liked it better than the red...
