This review is from: Cobra XRS 9840 Ultra Performance 12 Band Radar/Laser Detector (Electronics)
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.

This review is from: Cobra XRS 9840 Ultra Performance 12 Band Radar/Laser Detector (Electronics)
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.

This review is from: Cobra XRS 9840 Ultra Performance 12 Band Radar/Laser Detector (Electronics)
I've probably used this for about a year now. Still going strong. Saved my a** more than once. I think cobra makes some the best radar detectors in their price range. This one replaced my old cobra that was about 7 years old. I would say this one gives me about twice the warning time of my older one. It does a better job of picking up the radar signal when i'm approaching the crest of a hill. Highly recommended!
