I just purchased a Valentine One for my wife for our anniversary. When I asked her what she wanted the only thing she said that she wanted was a radar detector, so a radar detector it was.
I asked around and the V1 was the most recommended. I bought the Concealed Display and the SAVVY for a painless installation. It will be installed in her 2011 BMW 335is Coupe.
My previous radar detector experience was with an old Passport which I bought when I lived in Michigan over 20 years ago.
