It really boils down to where you do most of your driving. If the majority of your daily driving takes you past a lot of false alarms then the 9500 is for you. I started with a 9500i when they first came out, great detector. Then I kept hearing about how if you go V1 you'll never go back and guess what they were right. I've run a V1 since 2009.
