If Radar Roy didnt test it, then its not even worth looking at it.
BTW, in the last 3 videos, the radar detectors need to be mounted as high as possible on the windshield for best detection. Remounted all the radar detectors at the very top of the windshield and retest it.
I cant find a single independent K40 review. Very odd.
