I have owned radar detectors since I started driving twenty years ago. My first few were generic/off brand radar detectors and to my dismay, I finally broke down and paid a little more for one that I hoped would last a litlle longer. I was please to purchase my first Cobra Radar Detector at the age of twenty-one and have owned one since. I like the fact that they last forever and don't go off at every little electric door, yet let you know when a radar is around well in advance. I also like the fact that they stay up on the latest updates and technology and immediately came out with the wireless when it was developed. I have fewer tickets from speeding, especially when I remember to turn it on.
