Style: Laser Radar Detector
Great radar detector. Everything on it is automatic. Works great, and comes set up with different sounds for bands. I was afraid I wouldn't hear the Ka band alert when I'm playing music loud, but it's not an issue, the alert stands out!!

Style: Laser Radar Detector
Great radar detector!.. there's a you tube tutorial online that's very specific and informative in regards to set up and operational frequencies verbiage. It's expensive ( but so are those tickets, lol) but worth it! It's already saved me driving thru a black out area's of the freeway when CHP was hiding in the cut or driving behind me several times. Suction cup attachment to windshield is sturdy, frequency warning sound quality is distinct and exact, Enjoy👍 ... show more

  • Best of the best (with one caveat)
Style: Laser Radar Detector
Arguably the best detector on the market. The R8 is Uniden's top-of-the-line detector, it has very long range, has directional arrows, and has many customizations to help weed out false alerts. Bluetooth makes it easy to change settings via phone app. Be warned, the marketing material says this unit is not detectable by police using the Spectre I and IV radar detector detectors (RDDs), but real-world testing shows that the Spectre III and Elite RDDs can sometimes detect the R8 at close range. I'd go with the Escort Redline 360c or Valentine V1G2 if you need 100% stealth. ... show more

  • 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

  • Expensive but so is a speeding ticket
Style: Laser Radar Detector
K band I noticed picks up alot of the signs that show your speed on the side of the road and lot of other false alerts. I turned K band down to lowest setting which is 30% I think which helps but there still is false alerts, I wouldn't turn K band off completely just so you're not caught lacking ever but whenever I hear KA band that's when I lock in cause usually its pretty good at picking it up. Definitely a good radar but definitely pricey as well, I bought it on sale for $650 but I would recommend it. ... show more

  • One of the best radars available
Style: Laser Radar Detector
The media could not be loaded. After one year of owning I have been saved from countless tickets. The range is very far and it’s good at detecting false alerts. Definitely worth the money

Style: Laser Radar Detector
Fantastic spotting capability!! Only downside not many cops use their radar where I live so now it’s kinda useless for the most part but when traveling I’m bringing it with no matter what. It picks up everything and even tells you where the signal is coming from!
