Cops haven't snatched my crops yet.
The best radar detector for the price in my opinion. This is an upgrade from my R3 and it has exceeded expectations. So many features and user settings that I'm still learning about, but I'm sure any experienced person in the field of radar detection would easily know what to do with them. Its still easy enough to use for someone like me. Purchase this and you won't be disappointed, or ticketed.

Awesome little detector
I recently returned from a trip from Kansas to Colorado. My R4 worked flawlessly. Depending on the terrain, it picked up cops running radar anywhere from over a mile away to 3 and even up to 5 miles away. It’s the best radar detector I’ve ever owned. I just wish it was 100% true stealth. But other than that it’s awesome. And you just can’t beat it for the price. Escort should be ashamed of their radar detectors in comparison. I’ve purchased my last Escort radar detector. That company is a joke. I bought my R4 at Best Buy for just over $300 on sale a while back. I also use R4 companion and it integrates perfectly with the R4. It’s well worth the $10 for the app on iOS. I have this mounted above my visor with a visor mount i purchased from eBay so it’s also well hidden in my Mazda. Using the R4 with R4 companion and Waze is a trifecta of awesome counter-measures. I can’t say enough good things about the R4. Great job Uniden. I highly recommend this detector.

R4 Radar
Love this thing. Go through the settings and pick the write right setting for each mode. It may seem like it will go off all the time but thats either bc your filters arent right or it just picks up everything. And even if it does pick up everything it has an automute so it knows where the false alarms are if you constantly go past it.
