The K40 Calibre radar detector and laser jammer was tested by a group of enthisiasts called "The Guys of Lidar" from the popular radar detector and jammer forum http://www.radardetector.net.
In this video the K40 laser jammer failed to jam any of the police lidar devices that were shot at the vehicle during the test.
Also during the radar detector portion of the test the K40 radar detector performed worse then the $65.00 Cobra radar detector units that were also reviewed.
The K-40 radar detector antenna is manufatured by Escort Radar and is based on one of their models dating back to the early 90's.
The K-40 radar can be detected by the rdd devices police use to detect radar detectors such as the Spectre, so this unit does not live up to the manufactures claims of being stealth!
Dealers who sell/install this remote mounted radar detector pay $500.00 wholesale and charge as much as $2500.00 for a typical installation.This is much more than the Escort's newest model the Escort 9500ci that is completely immune to the Spectre and all other RDD devices and also includes GPS photo enforcement database along with automatic detection and filtering of false alerts.
Also the Escort 9500ci, along with the dash model the Escort 9500ix, have as much as ten times the range of this radar detector.
There are several websites that review this device in more detail such as http://www.RadarTest.com and http://www.RadarRoysBuyersGuide.com
