I've had this radar detector for a little over a year, and it has definitely paid for itself in traffic tickets. I tend to have a heavy foot when I drive, and this little thing gives me a little extra warning. Its easy to install - just stick the suction cup bracket on your windshield and plug it in. It detects a few different kinds of radar as well as laser, although if it does detect laser, its probably too late since that means you've already been hit with the gun to detect your speed. It does tend to give a lot of false alarms, especially when passing through areas with a lot of stores, etc that might have motion activated doors or alarms. However, I would rather get a few false alarms than get costly speeding tickets and spend time in court and get points on my license.
