Radar detector choices

Uniden periodically updates the database as cameras are added or retired.

I use an R3 and have been extremely satisfied with its performance. Alerts many miles before encountering the LEO are common place. The prior comments here about laser and instant on radar are well taken. Short of installing a laser jammer (illegal in many states), running Waze along with a RD are pretty effective countermeasures.
