I couldn't help myself when I ran across this. I rest my case on the "intelligence" of a Cobra user. Feel free to comment over at their forum.
"I was coming home from a long distance work trip back to my sister's wedding. I was doing a little faster than I normally do. The radar came off from the velcro and so I took it off. After seeing two people got pulled over, I decide to put it back. 10 miles left to home, my radar alarm me of Laser alert, I slowed to about 80 or so on a 65. I looked up and saw a vehicle stopped and then as I get closer, he started to move and came to the exit heading my direction. I immediately slow down to 70 while the guy behind me drives a VW Golf past me by. I thought the trooper was going after me but he kept on ahead and signal the Golf to pull over. That was a close call because I was in a hurry home for the wedding. This radar saves me a few times. It pays itself already!"
