The Valentine One is a famous radar detector among the top ten radar detectors. It’s well-known for its exceptional range, and it’s a classic design. Of course, there may be a distinction between having a typical layout and being stuck inside the past. The show and controls are embarrassingly dated for a modern-day radar detector, and the refusal to adopt GPS makes me surprise why it’s priced so high.
