I have a Talon mounted on my bike. It's forward facing and it's tricky to use so mostly I use my laser.
Being on a bike I am higher then the surrounding cars and I can see inside. Every time I see a detector mounted on the window I will slide into the blind spot of the car, so I can see the detector, and turn on my radar.
The driver usually freaks out(we are normally going 10 over, normal flow of traffic) and hits the breaks. After looking around for me, and not finding me, he will speed up again. I hit him again......
The fun never stops.
