4.0 out of 5 stars Does what it was designed to do ...., October 7, 2008

By	John H. Derickson "jay dee" (Dale City, VA) - See all my reviews (REAL NAME)

I took a recent 400 mile trip in to West Virginia from Virginia and this unit alerted me several times ... with enough time for me to check my speed and adjust accordingly. I picked up a moving police car coming up on my rear several minutes before the police car caught up with and passed me. So, in my opinion, for the money, it's a good unit. TWO things I do not like: I'd like to have a visor mount and I'd like to have a straight, fairly long power cord. For this reason I give the detector a 4.

2.0 out of 5 stars SAVE TIME AND LOOK ELSEWHERE!, February 19, 2009

By	Tommy Villegas - See all my reviews (REAL NAME)

My old and reliable Cobra Radar Detector went out and I decided to get this one. I don't know if Cobra made the newer models less sensitive or what. This model has no range and gives too many false alerts. Am sending it back to get a Beltronics Detector.
