  • Best I’ve ever used! Picks up Ka at loooong distance
Style: Laser Radar Detector
Best radar detector I’ve ever used. I did have to disable k band due to lane keep assist triggering it constantly but 99.9% of radars utilize Ka band so it doesn’t affect performance. Speed camera and red light camera alerts work well using its built in gps. 10/10 would definitely recommend.

  • So far no tickets
Style: Laser Radar Detector
Why did you pick this product vs others?: Value and performance. Accuracy: Very sensitive, it finds radar miles away and few false alarms particularly with Ka band. With the GPS it is able to learn where many of the Dallas alarms are abs self mutes in those areas. Great radar detector!

  • 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

  • over a mile warning
Style: Laser Radar Detector
Amazing the distance this thing picks up radar. Local police leave their radar on and I get alerts when I can't even see the vehicle because they are on the other side of a hill. I saw complaints about the wifi of the r8w - so I am glad I got the r8 - the only diff between the two is price and wifi. I hooked it up to my pc to update it and had no issues. HIGHLY recommend. ... show more
