About me- 3 or 4 tickets last few years, I had a Vector 940 that I gave up on because of all those false. Now I am back to a RD after a ticket about 2 weeks ago. So this time around no cheaping out and got one of the best. LOVE this thing after a quick spin last night, purposely drive past a false 3 times and it did the job as advertised. I am a rookie at this RD stuff so I will just leave it in auto and not mess with a single thing. I only really got this for the autolearn part and for it to be quiet as I drive by the Walgreens, Banks, a garage doors.
