Good Experience June 26, 2019
Reviewer: Larry from League City, TX United States  
I bought this detector and am very pleased with it.  I have not been out of town yet but it has done well within the city.  I had questions initially and found the customer support to be excellent.

Great Sensitivity November 24, 2018
Reviewer: Mitch bogle from Eglin AFB, FL United States  
I have been using my R3 for only a month. I still need to optimize my settings. Initial impressions are that it  has great sensitivity. I'm not a fan of muting the over speed limit function since it starts chirping immediately after it detects and alerts on a signal. Again, i still need to optimize my settings.

Sophisticated November 24, 2018
Reviewer: D. Stephen Nose from Mount Airy, MD United States  
As the radar sophistication changes, as well as automotive devices that put out false signals, radar detectors must also change.

I replaced a Bell radar detector that was approximately 15 years old and rendered virtually worthless with the constant false alarms.  I now have a sophisticated, upgradeable, working radar detector again.

Seems to be as rated November 21, 2018
Reviewer: mark from arl United States  
My last detector (from Radar Roy) was a Bel rx65 pro and served me well for over 10 years saving me hundreds of tickets and untold thousands of dollars. The R3 seems to be the modern equivalent with enhanced features and even better performance (I didn't think that was possible). Only have used it for a short time. It seems to rarely false alert and this itself is quite amazing considering modern vehicles are "spraying" radar and electronic signals all over in every directions. The few true alerts have come at great distances providing plenty of warning. Voice is clear and easily understood, display has all information in concise and easy to read format and there is a lot of information provided. Construction seems robust, has a quality look and feel. Love it has a smart cord just like my old Bel, but with aUSB outlet, nice. I expect just as long and likely better relationship than I had with my RX65. Great job Uniden!
