This is the second one I have had over two bikes. Total miles so far 73,000 coast to coast and Canada/Mexico zero tickets and quick rides always bumping the speed limits. The LED keeps me on notice, yet can be more than I need sometimes in Highway mode. This best test result I remember is a trip through Arizona two lane road, fast and fun with a few small rises just enough not to be able to see over, and following a car. As the car had just topped the rise my Laser when nuts and I slowed, then just a I hit the rise I saw why, a Trooper was lighting us up from a lower position and pulled the car over just after we passed. Now with Laser, mind you with Laser this is most likely the only time you can beat it. Because Laser has almost no warning as it is on and off and at the target. I can only guess that the Trooper was lighting up the car at the top of the rise and I was able to detect the hit. Any other time it has been tag your it and I must have been at the correct speed. They have a hemet notifier, but I have never bought it. It is meant to be a handle bar mount but it is ugly and has a ton of wires coming out of it, I do not recommend mounting it in the open.
