Good, Expensive

Jim BellowsDecember 14, 2025

Lots of software adjustments, options for filtering, display colors, sounds etc. Like all detectors I guess, there are a lot of false K band triggers from other vehicle radar blind spot monitoring. The Uniden allows adding a few ranges of frequencies to not trigger the warnings, but there is some risk in doing that in excess and missing a real police radar event. I only have one complaint that would not be an issue for everyone. I mounted it to a sand filled base pad, designed to sit on the dash and using high strength Velcro, which I did with my Escort as well. The bottom of the Uniden housing is not flat, making it sit crooked to one side or the other when snapped onto the Velcro. I know, picky. I'll have to figure out a way allow for the angle. Read more

Worth the price.

KOctober 25, 2022

This review is for the UNIDEN R8 radar laser detector. I have only had it for a few days. I read reviews on it falling off the windshiled. Mine came with 2 mounts. One of the mounts does look flimsy. It looks like my expensive unit will fall off if i use it. It did come with another mount that looks like I would have trouble removing it. I highly doubt this mount will fall off. It has a button so it can clip on and off the mount with ease. I'll problaby buy another of those mounts for my other car. So I used it to go to work. This thing was going off the whole entire time. Some people say you can tweak it. I will look into that later. For now I never read the instructions I just threw it on the wind shield. On day 3 the device memorized the false alarms. It still lets you know there is a frequency being detected but it grayes it out and no sound. So I was cruising to work the thing was quiet. All of a sudden it goes off I slow down. Im mad there is nothing. I want to return it. Then all of a sudden I see a hidden P car trying to catch speeders. On that road the fine is 350. I would have gotten caught for sure. So I already see it as 350 off. Like I said I never read the manual it was plug and play. It learned what was fake and it alerted me to what was real. Another feature I like is it tells you where the radar is. It was beeping showing ahead I never saw anything I just wanted to return it. Then it said it was on my left side. I looked and OMG on my left side behinid the barrels was an SUV just waiting to catch me. I also like that it shows your speed in digital format. My car has a needle speedometer. I dont look at that anymore. I just look at the R8. Its right on and accurate. This thing is pricey. In its defence I just took it out of the box and plugged it in. Like things should be. So yes i'm willing to pay a premium for something that simply works out of the box. Reviews did say that the LCD screen dies out so I bought the insurance just in case. In comes with a thin sleeve to protect it as well as a sturdy case. For now its 5 stars. I bought a unit before from another brand that required conection to my phone access to my contacts and gps and the whole nine yards. My car looked like a cockpit of an F16 i could not see anything out of the windshield. Im not sure if this thing has an app. I dont want an app and you do not need one. Plug and play its that simple. Just be warned the thing is a cry baby for the first few days as it learns what is real and what isnt. Read more

Outstanding Performance and Customization.

NickMarch 25, 2024

This detector is high quality, has great performance and allows a lot of customization to dial it in best for your use case. My only gripe would be the mute memory stopped working properly for my normal commute after I took a 1,000 mile road trip. This is a known issue however, that should get fixed via software update, which you have to do manually by plugging it into your computer. However, after deleting the mute memory in the spots where it wasn’t working and re-adding them, it’s working well again. I especially like that there’s a 3rd party R8 companion app you can add to you smartphone for only $10 so you can more easily change settings from your phone. The app can also add more advanced false alert filtering and “Spot Locks” which are like Auto Mute Memory locations but overcome the memory glitch in the detector because they’re managed by the app. If you turn the volume of the detector off and run audio through the app, then most audio alerts should he real threats instead of the other way around, which keeps you sensitized to chirps. The only thing this detector want do much for is Laser detectors because by the time that narrow beam hits you it’s too late. The best protection for laser is a jammer. The best on the market is the ALP laser jammer and the Uniden R9 laser jammer, but the latter requires the Uniden R9 detector system instead of the R8. If you don’t want to shell out up to $2k for a legit laser jammer, then just keep a car or two in front of you. If the laser is far enough away, the beam will mostly hit them but can spread enough for you detector to detect. Read more

Works great for me

W. HuberSeptember 2, 2025

This works great. I did a lot of Youtube review watching and it lives up to the great distance it picks up radar. I haven't had it pick up on lidar yet so I'm interested to see how it handles that. I like that you can mute repetitive signals and it will audibly tell you what band of signal it's picking up. It will pick up the radar that the latest cars use for crash avoidance but that's not a bother for me as it's not constant where I drive. The beeps get progressively quicker as you are approaching the source and exiting from it as the rear detector picks up from the front. I like it and again, it does pick up from a really good distance. Read more
