Customers are saying

Customers find value in the R3 DSP Long Range Radar and Laser Detector, particularly praising its impressive range and overall performance, which is comparable to higher-end models. Users appreciate its radar detection capabilities, accuracy, ease of use, and the inclusion of GPS for camera updates. While some mention false alarms and suggest turning off K band, the detector's size is considered reasonable.

    Works great! So far it’s been reliable at detecting speed traps. A little tricky to set up but works as it should.

    I purchased this over 90 days ago and use it on a daily basis! Radar has great range with a memory function for posted sign radar detectors to reduce repetitive alarms. With the laser and photo radar, this guy is amazing! I purchased a hardwire kit from Amazon for a low price with a bracket to mount to my rearview mirror! If you didn't know any better, you'd think it was stock.
