Was on the highway the other day with my 9500ix, and it caught a cop on top of the on-off ramp a mile ahead. Alarm goes off, I slow down, I start looking to see "where?" and as I pass the next exit I see the State Trooper coming down the ramp in my rearview. I was like "whew".
A laser caught me one time and it was game over. I got off with a warning. You really need L shifters to make that work. I just don't like the cost and the fact the self-install would be difficult. Oh well.
