The XRS-9955 is good product. I think the sensitivity should be increased. I traveled to Atlanta on last week and it alerted me several times. There were a few false warnings but they are minimal. For some reason the Alabama State Troopers and Mississippi State Troopers using a KA band that the detector doesn't pickup until you are 50 yards away. By that time it could be too late to decrease your speed. I think if the sensitivity was increased this would be a much better piece of equipment.
Great radar detector. I looked at several radar detectors before deciding on this. Both my wife and I are very pleased with the detector. Very accurate and picks up all types of radar. Again, very pleased with a super radar detector.
