Great product
This has been my first radar detector and I spent a lot of time researching different ones, so far I have not been let down. Am very happy how I can drive thru town and it don't make a sound untill it detects radar unlike the radar detectors some of my friends have, it also picks up signal from quite a ways off. So far I am very pleased with my purchase just wish I would have invested in it sooner.

Not only does it screen most annoying false alarms, when the alarm is real, you know it. The best aspect is no longer passing a speed trap and having the officer look at you because he knows you have a radar detector...it is like running silent and being a part of the flow of traffic. T in Colorado

Great Detector - never misses a beat
I purchased this unit for my new Porsche - most people pass me on the highway, since I have nothing to prove, and I guess they feel they do. But, I have noticed I was attracting the attention of law enforcement even when just keeping up with traffic (maybe they just want to pul me over to look at the car?). So I installed this unit (hardwired). Excellent detector. Never misses a beat - extraordinary sensitivity on the highway - the City NoX setting works like a charm. Highly recommend!

My Review of my Beltronics Sti Magnum
I just love this detector. The Magnum replaces my old RX65 which was a good detector but I was looking for more sensitivity and this unit did not disappoint. What I love the best is the immunity it offers when I travel outside one of the friendly radar detector provinces here in Canada. I would definately recommend it.
