I saw some disturbings reviews on a site called laserjammertests.com and wanted to see what I others saw. They using a LI against a Stalker Lidar and Laser Alley. These tests showed some bad results for LI. The question I have, is the driver of the car possibly turning on and off the manual switch during the test? Why I say this is because the dual sensor lights appears to "flicker" through out the run. Is this suppose to happen?
