Impressive Long-Range Detection
By Brandon on Reviewed in the United States on September 30, 2024
The UNIDEN R4 Extreme Long-Range Laser/Radar Detector is one of the best radar detectors I’ve used, offering excellent performance, reliable alerts, and plenty of features to keep you aware of speed traps and law enforcement presence on the road. Its extreme range and accuracy make it a must-have for anyone who spends a lot of time on the highway. Pros: Incredible long-range detection: The standout feature of the UNIDEN R4 is its exceptional long-range detection. It consistently picks up radar and laser signals well in advance, giving me plenty of time to adjust my speed. Even on wide, open highways, this detector can pick up signals from several miles away, which has saved me from speed traps more times than I can count. Accurate and reliable alerts: The R4 provides highly accurate alerts with minimal false alarms. It does a great job filtering out unnecessary alerts from automatic door sensors and other non-threat sources, which is often a problem with cheaper detectors. The advanced filtering technology ensures you get alerted only when it matters, keeping the ride smooth without constant beeping from false signals. Multiple radar bands covered: The R4 covers a wide range of radar bands (K, Ka, X, and laser), ensuring you’re protected from virtually any radar gun or speed trap. The inclusion of laser detection is a big plus, especially for drivers in areas where law enforcement uses advanced speed detection technology. GPS functionality: The built-in GPS is incredibly useful for storing your driving history, as well as for marking red-light cameras and frequently encountered speed traps. You can also mute alerts in certain areas (like near your home or office) where you know the signals aren’t threats. This further helps reduce false alerts and keeps your focus on the road. Customizable alerts and settings: The R4 comes with a range of settings you can tailor to your driving style. Whether you prefer quieter alerts, different volume levels, or specific radar sensitivity, this detector allows you to fine-tune the experience to your liking. I found the voice alerts to be especially useful as they allow me to keep my eyes on the road while staying informed of any nearby threats. Cons: Learning curve for settings: While the customization options are great, they can be a bit overwhelming for new users. The menu isn’t the most intuitive, so you might need to spend some time with the manual to fully understand and utilize all the features. Once you get used to it, though, the customization becomes a huge advantage. Tips for Use: Mount the detector high on your windshield: For the best range and detection performance, place the detector high on your windshield, just below the rearview mirror. This helps the R4 capture radar and laser signals from farther distances. Regularly update the firmware: Make sure to keep the firmware updated through UNIDEN’s website. The updates improve the filtering, GPS database, and overall performance, keeping your detector current with the latest threats. Customize the settings for local laws: Depending on your area, you may want to adjust the radar bands or sensitivity settings to align with local enforcement methods. This helps ensure you’re only getting the alerts that matter most. Overall Experience: The UNIDEN R4 Extreme Long-Range Laser/Radar Detector has been an absolute game-changer for me. It offers fantastic long-range detection, and its accuracy and advanced filtering system ensure you’re alerted to real threats, not just random signals. The GPS functionality and customizable settings are invaluable, allowing me to personalize my driving experience and further cut down on false alarms. It’s especially helpful for anyone who regularly drives on highways or in areas with heavy law enforcement presence. Though it’s a bit of an investment, the performance and peace of mind make it well worth the cost.

Best until was working
By Andrew B on Reviewed in the United States on May 15, 2025
This unit was my second one. Only lasted 2.6yrs.My first one lasted like 8yrs.both died in the desert where's about 125 i forgot to unplugging it at 110(outside temp was like 99...windshield temp. is diff. story) after parking the car and now the 3th time i have to buy a new one, this time i will try the R7. Don't miss understand me this is the best thing since a silece of bread but i think they can not handle heat. I drive in Ca. and AZ. Speed tickets are $499 and $299. this units save me at least twice or more every day...you do the math and i still have perfect driving record after 40years of safe driving up to 140 mph.(I am a European reject where we drive and would like to get there. I can not drive @65 fall to sleep so it's not safe for me) The reason i'm going with the R7 cause the dirrection of the radar. This r4 is warn you so much ahead some times takes me 10 minutes to find a cop if it's behind me.So simple\comes on push the break until speed limit than set the cruise control and when no more sound put your foot into the gas padle and burn petrol and go fast as you can until the next warnings! I got 232 miles door to door between my two homes last 3yrs i could not do better than 2.29hr do it 1-4 times/ month.On the average trip saves me 4-10 tickets.(do the math again) the reason for the 1 star is because it's should last longer than 2.6yrs. Keep it cool and unplug it when not in use, do not let it cook on the dashboard like i did.No one who likes to drive(worry about speed traps or saving $s) should be without one.
