    Cobra RAD 450 Laser Radar Detector: Long Range, False Alert Filter, Voice Alert & OLED Display

    • The false alarm filtering works perfectly and does exactly what I need it to
    • I haven't had trouble with the unit giving false alarms from automatic doors, etc, for the most part.
    • No false alarms.
    • The positives of it are that the power cord is long, it shuts off automatically when the engine turns off and hardly no false alarms
    • My old Cobra picked up false alarms like crazy from the blind spot sensors on newer cars.
    • great no false alarms
    • If you need a cheap radar detector with good range this is the one for you, the detection range is a little over half if a mile with little to no false alarms
    • So far it's a good unit, not many false alarms
    • They were still very capable of detecting police radar at excellent ranges, but the false alarms would drive you nuts
    • But it's really no big deal you can always hit the mute button since this system doesn't have the GPS lock out and won't be able to recognize businesses as false alarms
    • The nice thing too is that if you do get a false alarm its very easy to hit the mute button and the radar will mute the false alarm until you are out of range
    • I'm amazed how this blocks just about every single false alarm
    • I love that this one doesnt give false alarms constantly like my old one
    • I had zero false alarms
    • Works much better than my older Cobra model, with fewer "false alarms" and quicker "real alerts".
    • I was looking for a good radar that do not cost me an arm and a leg & will work proper without tons of false alarms
    • If you're in a parking lot, very near a door, it will detect it and alarm, but you've got to be pretty close, I haven't had any issues with it false alarming while I'm actually out on a highway.
    • I’m keeping it permanently on City mode, which cuts out all but the very strongest X-band signals to cut down on false alarms from auto-door openers and the like (I don’t think any police in my state still use X-band), and that way, I can be pretty certain that if it goes off, I’m sensing either K or Ka band radar from either a cop or a radar speed sign.
    • I get no more than a quarter of the false alarms as my Bel RX65, and unlike that higher priced unit, it doesn’t go nuts when I’m near a new premium vehicle (especially an Audi) that has collision-avoidance radar sensors; its IVT (In-Vehicle Technology) filters really work and most of the time I can drive by Walgreens and gas stations that normally set off my RX65’s alerts, but the RAD 350 ignores them and stays
    • I get false alarms when I am around semi trucks and automatic door openers
    • The nice thing too is that if you do get a false alarm its very easy to hit the mute button and the radar will mute the false alarm until you are out of range
    • I'm amazed how this blocks just about every single false alarm
    • I love that this one doesnt give false alarms constantly like my old one
    • Doesn't seem to pick up a lot of false alarms.
    • Compared to my old beltronic that I had payed $175 and had its share of false alarms
    • So far it's a good unit, not many false alarms
    • This model advertises giving fewer "false alarms" for electronics in other vehicles, and I think it lives up to that claim.
    • no complaints here had to turn off the X band because I was getting a lot of false alarms from other cars anti-crash / blind spot warning systems
    • My friend has the equivalent belltronics one and his goes off with false alarms constantly
    • great no false alarms
    • Less false alarm !!
    • Really got tired of all the false alarms with my old radar detector
    • With other detectors I’ve owned, their alarms are quite distinctive and it’s easy to tell the X from the K from the Ka bands.
    • I used it for 10 days and so far had only one false alarm and 3 nice, advanced warnings (1 on a highway and 2 driving in town).
    • false alarms is unbelievable
    • Super long range, little to no false alarms
    • Very few false alarms
    • Less false alarms.
    • I’ve gotten so many false alarms
    • so she got lots of false alarms
    • This one has a few false alarms, (ie some store doors, construction equipment?
    • Very few false alarms.
    • My wife went form about 20 false alarms a day on her drive to work, due to Yukon and other trucks on the road bank doors etc
    • In day light, even on a cloudy day, not just with the sun shining directly on the unit’s face, all four of the icons glow as if they are all equally lit up, and when the detector detects radar, the particular band it detects is no brighter than the other icons
    • Disappointing as it was a Father’s Day gift
    • it is easy to use, and works (worked) as it should
