Uniden DFR7 Super Long Range Wide Band Laser/Radar Detector, Built-in GPS w/Mute Memory, Voice Alerts, Red Light & Speed Camera Alerts, OLED Display, Black

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 for filtering 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 which car 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.

Great little baby! Saved me a lot! I’ve got a Mustang GT 2025 and rally it on long trips! This worked like a charm! Gave me plenty of time to slow down and waive at the cops, then punch it again! Fun and Fantastic!!!

Great product for the price. If you're buying this to stay clear from speeding tickets, then you're buying the right detector. So far, I've been safe from any type of tickets. The reason I can't give 5 stars is because of false radar detections. While there are filters, the functionality of the filters aren't great. The K-Band is almost ALWAYS false. While the detector still detects the real radars, it is mostly false detection (from other car blind spot warnings or even automatic doors at shops). I was nervous about the mounting ability, but it turns it that the suction cups mount it firmly. The audible warnings are clear and loud. You're able to mute the warnings and turn down the volume if you wish. The GPS functionality is absolutely amazing, with its own speedometer and red light camera warnings. The OLED display even tells you how far away the cameras are.

With all the damn speed cameras in Chicago, this is a MUST OWN. Plus it's saved me a few speeding tickets. Worth every dollar. The quality of this radar detector cannot be understated. I spent weeks researching this off rdforums.org. Guys there go and buy police issue speed detection equipment then test out radar detectors an a obstetrical course. So you get unbiased raw data with plenty of things to learn about owning a radar detector and how to understand the readings. I highly recommend going there and spending sometime to understand it as it' lot more detailed than you'd think. On open interstates, the distance it will pick up signals is ridiculous. You see police long... before they know you're coming. Local highways is a life saver especially if your local expressway tends to double as the daytona classic. Local suburbs and city it does surprisingly well. About false readings -- K band in general can be a mixed bag. Automated doors at grocery stores, walgreens, and hotels will all set it off. You don't want to disable it as some cities still may use a mix of KA and K band. Knowing this you tend to mute those points as you do get 100 mute points which will save it from chirping when you're on your home turf. This does not auto mute these points like the $600+ units with slightly better detection. However, having the mute function on the power cord makes it nice and convenient. As for mounting this? I don't like the mount kit they give with this. Grab a sticky pad (https://www.amazon.com/dp/B01552AYD0/ref=cm_cr_ryp_prd_ttl_sol_5) and just lay it on it. Works great. Even if I had to do some sudden breaking, does not move an inch.

this item does not tellyou where radar cameras are it only works in the usa or canada ihave triedit and sent it back

Worked flawlessly out of the box, saved me from speeding cameras by early warning detection on my last trip
