Valentine One/2 - from left to right, volume control of the audible signal of the detection of a radar signal with the mute volume control, number of signals detected (up to 8), and direction of signal (radar trap ahead or behind). Note this detector looks both ahead and behind and displays detections on the central portion on the face of the detector.

The the US motor magazine, Car and Driver, says the Valentine One/2 "has dominated every high-end detector test we've conducted since its introduction in 1992". The overall ratings for various radar detectors from tests done in 1992, 1994, 1997 and February 2002 show the Valentine regularly comes out on top.
