Pros and Cons

Last but not least, we will include some pros and cons for the Uniden R3 and the Uniden DFR9.

Uniden R3

Uniden R3


  • The range is amazing, even when you are in hilly areas
  • There is an LED light that flashes faster the closer you are to a radar
  • It is easy to set up


  • If you don’t use the settings correctly you will get a lot of false alerts

Uniden DFR9

Uniden DFR9


  • Still has an excellent range on it
  • Reliable and early detection
  • The GPS is highly accurate


  • It doesn’t always remember the false alert you program in

The Final Verdict

The Uniden R3 and the Uniden DFR9 are very similar and either one you choose; you will save a fortune on speeding tickets. The GPS technology is very accurate on both and the detection works very well. The design and setting up/use of the radar detectors are also identical with the exception that the Uniden DFR9 is slightly smaller.

The OLED screens are also the same, the Uniden DFR9 has a tiny advantage that it has auto dim so it will adjust itself to the light. But that being said, you can manually adjust the screen on the Uniden R3.

With all that in mind, we decided that the Uniden R3 outdid the Uniden DFR9 in just two areas. The range of detection with the Uniden R3 was much better and we motived that you had so much more time to reduce your speed. We also felt that the Spectre Elite Undetectable was a feature that was well worth having. Although the Uniden R3 is more expensive, these two features made it worth the extra money.
