Got the V1 for about a week now and had it in the car for the same amount of time. I have to say that I am amazed by the performance. I clocked about 2000 - 3000 cars both front and rear all fast I/O and V1 failed to detect 2 of my shots. That is simply incredible when you know that the Redline would detect about 5% of my shots and only in high reflective areas.
As I was coming back in my personal vehicle with the out of the box V1, I got hit with I/O with no warning whatsoever and the V1 easily detected it while the Redline failed to alert.
Also, when I was following my co-worker, I picked up all of his I/O shots with the V1. That one time he was about 5 miles behind me and I was still picking up his I/O shots.
Laser is also amazing, V1 alerted to all laser shots for direct hits and also alerted for a rear shot.
Long story short, I am completely sold to this unit and will be using it in combination with my STiR Plus in my personnal vehicle. (I will not use it in the city though, only on the highway)
