I have the V1, mounted just to the right of my rear view mirror. I think it's the best radar detector you can buy, but I have 2 issues.. nothing really towards performance.
1: What's the point of the remote display if you have to mount the radar on your windshield to use it??????
2: Drive behind a Chevy Trailblazer or Envoy in a traffic jam and tell me what you think of your laser detector, anyone who has happened to see what happens when you drive behind one of these will know that the top brake light sets off the laser, which is the most obnoxious sound ever... as it needs to be, but not for a trailblazer....
