Style: RAD 450
This was my first radar detector and will be my only for quite awhile and bought May 2018. I drive an FJ Cruiser and only go average 10+ over driving in places like Illinois, Indiana, Kentucky, Tennessee, Georgia, and Florida on highways, interstates, and back roads. I also take it with me when I travel GOOD: Range - very long and has saved me many times from not seeing cops behind hills and whatnot while still being able to read other drivers' reactions near hills Alerts - I leave it on the highest sensitivity and only get a few random alerts - after driving with it for awhile I can pick out what is real and what is false based on the strength and type of signal its receiving. It does not sense other signals from cars like blind spot, nor does it give out any signal to police indicating you have a radar detector. Value/Dependability - I guarantee I would have been stopped at least 10 times with cops wasting time and money by sitting in medians and behind hills and such but this thing alerted me very quickly and allowed me enough time to determine if its false and slow down accordingly. This is one of the best $120 I spent on an accessory for driving besides a dash cam which I have written a review on too (Garmin 55). Usability - I use it every time my trip is longer than 20 min and goes through roads I'm unfamiliar with. It has sat in my truck basically since I bought it in the sun with temps ranging from 110 to 0F and starts up every time I turn it on and only shuts off if the truck's battery voltage drops below some threshold. The screen is very bright but goes into a dimmed mode after a few minutes of detecting a signal. Wiring/Mounting - I bought the hard-wiring kit and add-a-fuse and also a custom switch so I can turn it on with the push of a switch without having to reach and turn the dial switch on the detector. I also velcro'd it to the top of my instrument panel as shown in the picture because the suction cup kept coming off in the heat, it was easier to see on top of the instruments, and it was more stealthy for police to have less of a reason to pull me over since i don't use the suction cups. I have left the dial at the 6 on-volume position ever since I hardwired a switch. Noise - the noises of each band are to me pretty distinct and able to be remembered after awhile of using it. I discovered the laser feature only once when driving on a Florida highway and it does sound like a retro laser, but have not heard it again since luckily. BAD: I literally cannot think of any bad thing besides the fact it uses a 12 volt dvd player style power connector instead of mini usb or a more common connector. It does have a micro usb connection on the side which I just remembered and have not figured out what reason it could possibly need to connect to a computer for. Overall, I love this radar detector. Its sensitivity is just right and can be adjusted, it has saved me plenty of times and its value surpassed tenfold at least by the amount of times I could've gotten in trouble. Very easy to wire and mount if you know what you're doing. Great first radar detector.

This radar/laser detector works 100% exactly as it should. Very accurate and works at great distances. The reason some have given it 1 stars saying it didn’t detect a police officer. The reason for this is because not all cops have their radars on. Cops are highly trained to be able to look at a car and determine an average speed. If the officer does not have his radars on it WILL NOT detect it. It’s impossible for any radar detectors to detect one that isn’t turned on. Therefore it will not beep saying cop ahead. I come from a family of town cops and state troopers and tested the equipment on various speed detecting equipment and various bands. The device found every single one of them before the cop cars detector scanned me giving me time to slow Down. The rear scanner on the device works just as good AS LONG AS it has a clear view to the back. For laser detectors that cops sometimes use they HAVE to be parked and not moving for it to get your speed. The reason is because the laser beam is very small and narrow and must hit the car directly for it to register a speed making it 80% more accurate. This detector should be mounted in the very center bottom of your windshield for best use. The reason for it to be placed in the bottom center is most speed trap lasers are lower to the ground for best accuracy meaning the laser is pointed at the hood/front bumper of your car. Having the device in the center bottom gives it about 90% more chance of warning you sooner. With radars the police use it’s a large dispursment of radio waves making it very easy for the radar detector to find. The amazing thing about this detector is the fact it has a great system to determine if it’s a cop or just a door near by. I have so far never had a false reading in town unless I had the sensitivity on high. Finally, those who say they get false highway readings. Your not. 1st off there are hidden speed cameras. 2nd Cars and simitrucks can set it off. Why? Well, that is because most new cars and almost all simitrucks have radar systems that help them detect nearby cars to alert you when not to merge over or if your swerving. These radar systems in the trucks and cars generally use a K band signal at 24.75hertz. Passing a railroad crossing can almost always set it off. Rail roads have radars to detect cars to send information to the trains conductor to know he needs to blow the horn and lower the arms on the tracks. The signal is different state to state but in South Carolina about 98% of railways use X band. I hope this review helps sorry it was long just wanted to properly explain the detector to everyone!!!

If you’re looking at a radar detector we already know why you want it, you speed and want to minimize the chance of getting a ticket. There are always people who say you should just go the speed limit and not drive like an ass, but let’s be real, that’s not going to happen. I’m a mechanic for an Audi dealership, and to remain employed there I can’t get a lot of points on my license. They know that being a mechanic means you love cars, especially fast cars, so when you can, you’re going to push it. This radar detector is nicer than most in my opinion, it doesn’t have a long startup that deafens you, and the range is fairly good too. I get X readings when I come up to some intersections, didn’t read the manual so can’t help you on what the X means, but it throws up K alerts when I go by automatic doors, speed signs with the digital speed that you’re going, and some others. However the only one that really matters is the Ka reading, alerting you that a cop (mostly cops) are around, so slow down and don’t get pulled. It’s helped me out several times already, all within a mile, but it let me know around long bends, further up the road at night, basically just doing what it’s meant to, and for the price, it’s good quality. If you’re younger, or just don’t want to drop an absurd amount on a radar detector, I’d recommend looking into the Ckbra RAD450

This is a very good budget friendly detector and worth the money. It picks up radar from a good distance to give you some time to slow down, the rear detection is also good. It does send out false alarms, but the good thing about it, it seems to know they’re false alarms and it won’t stay alerting you for a long time. I also had the Uniden DFR7 and it had 3 times the amount of false alarms than the 480 and it wouldn’t quite down till you’re far away. This 480 gives you a lot of extra features that are worth it for a more than basic radar detector. If you’re choosing between the DFR7 or the Cobra 480, the 480 is way better. The hype of the DFR7 from enthusiast, that was 10 years ago, not now, you’ll be disappointed. The 480 is going to be a solid detector for everyday use and for drivers that don’t have a heavy foot. The only reason for the 4 stars is, the power cord could be a little longer. Save the extra $100 dollars and buy something for yourself or use it to buy the newer Cobra 700i that is updated and better.

My old radar detector was at least 10 years old and would go off ALL THE TIME. The new adaptive cruise control and blind spot monitoring was constantly giving me fits in trying to figure out if it was a false positive or the real deal. I knew i would be doing some long distance traveling (6 hours each way) and wanted a new unit to help minimize false positives so I purchased the RAD450 a little over a week ago. This unit is awesome! I used it for a couple of days in a small town that has lots of shops with security alarms and several construction areas with radar units that flash your speed to let you know what your speed is and it does great. The shops are almost always on the X band and filters it, alerts you, and then slowly disappears. The radar units in the construction area are using K/Ka band and it detects them both at a very reasonable distance (between .5 and .75) even in heavy traffic. I get on the highway for my trip and within an hour the RAD450 detected a Ka band radar being used. It started with the single block and worked it's way up to 5 blocks over the course of about a mile. Sure enough, a state trooped was running radar heading East bound while i was traveling West. In total, i passed 7 State Trooper over the course of 12 hours and each time it picked them up with plenty of time to slow down and get closer to the speed limit. VERY, VERY please with this unit and the accuracy it has so far demonstrated. I would HIGHLY recommend this unit to anyone in the market for a new radar detector. The only downside to this unit is the mounting. I don't like the multiple suction cup mounting that generally comes with most radar detectors. I would like to find a large single suction cup that mounts to the windshield and is easily detached by flipping a lever but i can't seem to find one for this particular unit.

I finally upgraded my 10+ year old Whistler unit with this Cobra RAD450. The 10 year old detector was "falsing" constantly thanks to the K-band electronic mother-in-law systems (so-called In Vehicle Tech or IVT) on pretty much all cars post 2017. In contrast, the RAD450 has been quiet as a mouse. It rarely if ever falses. Only when pointing directly at a door opener at the grocery store will you get some K band falsing. Otherwise it has been superb. The cops around here only use Ka band and LIDAR for speed monitoring. The Ka sensitivity is very good, about twice the range of my previous 10 year old unit. I have plenty of time to slow and often I don't even see the cop for 1+ minutes after an alert. My favorite feature is the "screensaver": a little white line slides back and forth, NightRider style, across the unit. It lets you know that it's working without being intrusive at all. My only complaint after using the device for a couple months is that I'd like the option to change which sound is assigned to which alert. Right now the Ka sound isn't nearly as attention grabbing as the K/X band sounds, and I'd like to change that. Maybe a software update could fix that? Otherwise, I think this is great value if you don't need GPS and other fancy features on the high end models.

This thing is great! While it's not a guarantee against getting caught speeding, it does help! I have a 25 mile commute each way to work, mostly open highway, and it has, so far, warned me about cops with radar going almost daily. You do need to keep in mind, this gadget can only sense radar or lasers that are in use... so if a cop suddenly turns on the radar, and you're within range, you're outta luck. Lasers are tricky, too, especially if you're on a road that's not really busy... if there's no one ahead of you, you won't get warned until it's too late. I haven't had trouble with the unit giving false alarms from automatic doors, etc, for the most part. 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. Only in parking lots. So it's not perfect, no way for it to be. But i'm very happy with it, and am buying a second unit for my husband's truck.
