  • Worth the price.
Style: Laser Radar Detector
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. ... show more

  • Lives up to the YOUTUBE reviews - but better.
Style: Laser Radar Detector
The R8 is the 1st radar detector I've bought in about 10 years. The last being an Escort- that I believe was the first advertised undetectable radar detector. Driver STi, I think was the model name It was a GREAT detector for it's time, but over the years it became nearly unusable with all the false alarms it gave. Flash forward to this last week. It arrived on a Tuesday, it's Saturday morning now. 3 days of commuting to and from work in use. At the end of day 2 it had the GPS lockouts set. Perfectly. It's a 20 mile drive each way. About 4 miles are street traffic driving, the rest is interstate. Some YouTube reviews observed issues with the GPS lockouts feature. Maybe the firmware was updated for mine? IDK. But no issues with that whatsoever. Until I got the R8, I was - and still am- using the WAZE GPS navigation app.. WAZE is a fantastic app to notify drivers of road hazards and police presence in moderate to heavily trafficked streets and highways. But it's not that great in more remote areas or the wee morning hours for police alerts- or what if YOU are the 1at person to come across a freshly set radar trap? It's virtually useless then. That's where the R8 is worth it's weight 8n gold. UBIDEN engineered the R8 to have future Bluetooth connectivity to work with 3rd party app developers AND they are also working on a laser jammer add on device for the R8 as well.. Laser jammers aren't legal in all states. Do your homework on your area before you let that feature become a purchasing factor. In my area, X Band isn't used, so I turned that band off. I have it sweeping the entire K and Ka bands, including POP alerts. I keep it on the HIGHWAY mode. False alerts are very minimal and very shortlived. I suspect that the falses are coming from other cars using those bands for their own driver safety assistance features. There's filters for those band segments, but those alerts are weak and shortlived, I would rather have a hundred of those unobtrusive alerts than miss 1 real alert. I highly recommend watching the YouTube set up videos on the R8 and check out the recommended settings links that explain all the different settings use caaes to optimize your R8 experience. It really is a fantastic detector. I bought it through Amazon with the optional 3 year warranty. I don't expect problems with it, but you know the saying - Is rather have it and not need it than need it and not have it. Again, check out the YouTube reviews, they're spot on, but now with excellent GPS lockout performance, where that has apparently been an issue before. If you can afford it, get it. It's really all you need. Plug and play with a few minor tweaks, set it up once or twice and forget it. No app necessary. ... show more

  • Best on the Market 2023-2026
Style: Laser Radar Detector
Highly recommend checking Vortex Radar channel on Youtube for help with setup and configuration for your area and needs. Definitely update this regularly, it is feature packed. No issues after 3 years in the summer heat. Display is perfect and can be configured multiple ways. Audio quality is great, and customizable. Durable and for the most part sticks to the windshield good, although it has fallen in extreme heat once or twice. No damage when that has happened. 10/10 would buy again, zero complaints or regrets. Best detector on the market 2023-2026. ... show more

  • Stay Ahead of the Road with Unmatched Precision
Style: Laser Radar Detector
I've been using the Uniden R8 radar and laser detector for a while now, and I can't imagine driving without it. It's like having a sixth sense on the road, keeping me aware of potential speed traps and red-light cameras well before they're in sight. The dual antennas with directional arrows are a revelation, giving me a clear picture of where any threat is coming from, whether it's from the front, back, or sides. It’s comforting knowing exactly which direction to pay attention to, thanks to the clear voice alerts. One of the standout features has to be the GPS technology, which does an impressive job of filtering out those annoying false alarms. It automatically mutes known false alerts, like those pesky retail store doors, so you're not constantly bombarded with unnecessary noise. It’s like the device learns as you drive, making each trip smoother and more pleasant. The built-in database of red light and speed camera locations is always up to date, thanks to free firmware updates, which means you're always covered. Another aspect that makes this detector a joy to use is the large, multi-color OLED display. It's bright, easy to read, and presents a wealth of information without being overwhelming. Whether it's the band type or signal strength, it's all there at a glance. And let's not forget the hands-free voice alerts, they’re customizable to your style, so you can keep your focus on the road without distraction. If you're new to radar detectors, I’d recommend a quick online search to find the best way to configure it for your driving environment. There are plenty of tips and guides that can help you get the most out of this device. Plus, the included app makes it easy to tweak settings and receive real time notifications on your phone. All in all, the Uniden R8 is a reliable co-pilot that enhances your driving experience, ensuring you're always a step ahead on the road. ... show more

  • Faulty Radar!
Style: Laser Radar Detector
Radar was okay at first. When paired beside another make of radar, it didn’t measure up to its standards. After about a year, the radar became more inaccurate, sometimes not even detecting the police. Now, the radar doesn’t work at all. It won’t even turn on. Customer service is terrible. They won’t help you at all until you send them over $100 to take a look at the device. They won’t even pay for shipping and handling, even though they state that I could have received a bad device. 10/10…DON’T recommend! ... show more

  • Best INVESTMENT EVER!
Style: Laser Radar Detector
I was hesitant at first about spending so much on a radar detector, but after thinking about my driving habits, I realized I needed one—ASAP. Within the first month of owning it, it already saved me from getting a ticket. The range on this thing is insane—almost overkill, but in the best way possible. Quick story: I was going slightly over the speed limit on a notoriously strict road (seriously, cops everywhere). The detector picked up a signal about half a mile ahead, so I eased off the gas. The guy behind me didn’t take the hint and blew past me—sure enough, moments later, he got pulled over. I cruised by without a problem. I've had this for about 2 years now, and it's saved my skin more times than I can count. If you're still reading this—stop. Just get it. You won’t regret it. ... show more

  • Excellent Detector
Style: Laser Radar Detector
Hadnt owned a radar detector in decades. Read something about detectors and was curious what was on the market these days. Looked like the Uniden R8 and the Escort Max 360 were the top choices. Hit youtube and did some research. Decided on the R8. Pretty staggering price, because it always seemed like it takes about $300-350 dollars to get out of a typical speeding ticket, and you logic out how a $300 detector will pay for itself on the 1st time it alerts you and saves you. Well, this one will have to save you a couple times to justify the $700 price tag. Have had it for a couple months now. The main redeeming part on this expensive purchase is Ka band detection. It is beyond good. The range of pickup is exceptional. They stole the idea of arrow display to tell you which way the radar is coming from, from the original Valentine One detector.....but it is essential in helping fine tune your conclusion of which way the threat is coming from. X and K band are probably only good if you are traveling through Mayberry, where older technology radar guns are probably still in existence. Laser is worthless. It just confirms a ticket for you. Ive actually been lasered once with this detector. But, the cop had his Ka signal going in the background, so it tipped me off to pay attention that a cop was in the immediate area and make sure my speed was in line, and THEN I got hit with laser. If that Ka signal wasnt going in his car, thier laser would have gotten me. So, once again, laser detection is worthless, its too late if they laser you. Its all about the Ka band. As far as the look, it is chunky. But in a great way. The display window is large and angled towards the driver. I literally like it more and more everyday I use it. All the displays are understandable and easy to quickly reference with your eyes. I can't imagine the Escort 360 could be better than this. Also, I saw people complain that for this price, the shell of the unit should be metal, and not plastic for the price you pay, and it made it feel "cheap". I never felt like the plastic was a deal breaker. Looks nice, feels fine. Not an issue for me. The suction cup mounting bracket has been a problem. Been dealing with high heat days and then a cooler night and have come out many a morning to leave and the mount is lying on the floor. The last thing you want is a $700 radar detector falling (maybe the plastic could be a problem?). But i must have gotten a good seal recently, because it hasnt fallen in weeks. Another VERY important thing, my STRONG advice, RUN THE WAZE APP ON YOUR PHONE IN COMBO WITH THIS DETECTOR. They work extrenely well together. When one has a weakness moment, the other covers it. These 2 together are formiddable! And Waze is FREE. So, I would highly recommend this detector. Hope this helps in your decision☺️ ... show more
