I purchased my first V1 on 8-7-1997. I drove from MI to pick that one up. Today I woke up at 4 A.M and drove down and exchange/upgraded to a new one 3.891 and a concealed display to go with it. The drive down was very uneventful till the last 30 miles in Ohio. On the trip back home I seen more speed enforcement in one day the the rest of my life. Holiday weekend brought them out in groups in all states traveled. I should have purchased the concealed display for the old one I love it. I used My escort 8500 for the last few years, and after driving home with the new V1 I wish I would have upgraded sooner. I forgot how much the arrows help. One thing I didn't like was when I first Hooked it up in the parking lot at Valentine research It alerted to X band for most of Ohio even in open fields,Michigan was not a problem. Great saves on all bands, even one encounter on X band. The One Michigan encounter was a State car in the middle behind trees using K band I did not get any warning good thing I was not the first car in the pack.
