Excellent product

Funziona solo con alcuni metodi di rilevamento della velocità. Sconsigliato

Nulla da fare...prodotto deludente e inutile...non rileva autovelx fissi, figuriamoci i mobili...ma cosa più grave non segnala autovelox-tutor con il rapporto della velocità media!!! La verifica è stata fatta sul territorio italiano...per l'estero non saprei!Restituito...

Das Gerät sieht NULL Blitzer! Mobile, feste - egal. Absolut unnötiges Ding.

detecte les camera des feux tricolors a present il ne detectepas le lidar a voir

Ich bin enttäuscht weil Habich kein Deutscher Beschreibung gekricht ,und dass Geret reagieren nicht auf Schtacionare Blitzer.Aber ich bin bereit neue Warner GPS Genevo +zu kaufen vir 179€ wen Sie mie der Cobra 450 kaufen als Gebrauch Geret. BITTE UM ANTWORT 😉

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 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!!!

In a nutshell, the Uniden gets an A+, the Rad450 a B+. Of course the uniden is twice as expensive so it should be better. But The RAD450 performed quite admirable for it's price. It is not quite as sensative as the uniden facing forward. For cops coming from the behind, the uniden definitely seems more effective. It takes awhile to figure out what is the best settings for these units. Both of their directions are decent but could be better. If you want to just set it and forget it use #5 for the uniden and #6 for the RAD450.The "quite ride" for the uniden works with the GPS speed. on the unit No sound below a certain speed. This works perfectly forfiltering out useless parking lot and stop light false alerts. Because the uniden can also mute specific locations it is even more versatile for filtering falsie's. I did not use this in any of my tests. Because the RAD450 doesn't have GPS, it's "quite ride" works differently. An audio will sound for a few seconds (2 or 3 beeps) then go silent. If it doesn't have a 30-40 second space between alerts, it will remain silent even if it gets a new alert (it will always display the alert). This works quite well for parking lots since you are getting many multiple alerts rapidly. Yet, this shouldn't be a problem while driving highway or city. In the driving test below I had all kinds of falsie's on the old radar including the blind spot radars used on cars. While following a Chevy equinox on the highway, my old unit cycled on and off continuously while behind this car. Both the uniden and RAD450 were totally silent. They didn't register any alerts. Other cars caused the same thing in my old unit but I couldn't identify whichcar was the source. The other 2 units remained silent.I was fortunate that the day of testing, Cops were everywhere so I got good data. I didn't get the actual distance on the city speeding trap, but both the Uniden and RAD450 were equal distances and gave enough warning to slow down. The old unit gave maybe enough warning. In summary,the uniden is a terrific unit. Spending anymore I think is a waste of money. If you can't afford the $250 price tag, the RAD450 is a pretty good unit and option. Anything cheaper than the RAD450 will most likely behave just like my old 7000 which is rendered useless due to falsie's.Also, as an aside note, the "intellimute" option on the RAD450 does not work on a 2004 Lexus rx330. Supposedly, the unit can tell the RPM of the engine through voltage spikes in the electrical system. My guess is that it won't be able to read most cars so don't count on this as a useful filter option. Regardless,The RAD450 works well enough for the price. So, I am keeping both; The uniden for my main car, and the RAD450 for my second car. I should be well protected in both less all those annoying falsies! Hope this review helps.
