Are radar detectors still worth buying in 2025?

Across the reviewers we read, the consensus is yes for drivers who do a lot of highway miles in states where radar (especially Ka band) is still in active use, but with caveats. Specialist communities repeatedly note that laser (LIDAR) is essentially instant, so a detector mostly warns you about radar threats and helps you spot speed traps further down the road rather than reacting to a laser hit.
